Prestižna nagrada Hrvatskim matematičarima

Hrvatski matematičari prof.dr. Zlatko Drmač sa zagrebačkog PMF-a i prof.dr. Krešimir Veselić emeritus na Sveučilištu u Hagenu (Njemačka) zajednički su osvojili prestižnu nagradu Linear Algebra Prize 2009 koju svake tri godine dodjeljuje međunarodno Društvo za industrijsku i primijenjenu matematiku SIAM za najznačajniji doprinos u primijenjenoj linearnoj algebri u posljednje tri godine.

Profesori Drmač i Veselić su nagradu dobili zbog otkrića brze i točne numeričke metode za nalaženje singularnih vrijednosti matrica (tzv. Jacobi SVD). Metoda nalazi primjene u mnogim područjima znanosti gdje je nužno brzo nalaženje vlastitih vrijednosti matrica, na pr. u fizici, tehnici, računalnim znanostima te u socijalnim znanostima. Istrazivački projekt financijski je podržala zaklada Volkswagenstiftung.

Zbog značajnosti metode, ona je uvrštena u najnoviju verziju LAPACK, najznačajnije i najraširenije računalne biblioteke matematičkih rutina. Ovaj uspjeh je plod intenzivne dugogodišnje suradnje profesora Veselića s profesorom J. Demmelom, UC Berkeley, kao i s više hrvatskih matematičara koji su se specijalizirali na njegovom institutu u Hagenu i onda se vratili na Sveučilišta u Hrvatskoj gdje djeluju kao nastavnici i znanstvenici. Profesor Drmač je doktorirao pod vodstvom profesora Veselića u Hagenu u Njemačkoj. Profesor Veselić je studirao matematiku na Sveučilištu u Zagrebu, gdje je i započeo svoju nastavnu i znanstvenu karijeru.

Profesori Drmač i Veselić su među  suorganizatorima serije konferencija IWASEP koje su posebno posvećene proučavanju pouzdanosti u računu vlastitih i singularnih vrijednosti.

Iskrene čestitke dobitnicima narade i mnogo novih uspjeha u daljnjem radu!

  
Prestigeous award to Croatian mathematicians

Croatian mathematicians professor Zlatko Drmač from the Mathematics Department of PMF in Zagreb, Croatia, and professor Krešimir Veselić from the University of Hagen, German, won a prestigeous 2009 Linear Algebra Prize which is awarded every three years by the SIAM (Society for Industrial and Applied Mathematics) for best scientific work published in the course of preceding three years.

Professors Drmač and Veselić were awarded for their discovery of fast and accurate mehtod for finding singular values of matrices (the so called Jacobi SVD). The method finds its applications in many areas of science where precise computation of eigenvalues of matrices is necessary, like in Physics, Technics, Computer Sciences and in Social Sciences. Their research was partly supported by the Volkswagenstiftung.

Because of its importance the method has been included to the newest version of LAPACK, the largest and most important computer library of mathematical routines. This success came as a result of intensive collaboration of professor Veselić with professor J. Demmel, UC Berkeley as well as with several Croatian mathematicians who specialised at his institute in Hagen, and then returned to Croatian universities where they act as professors and researchers. Professor Drmač defended his PhD under supervision of professor Veselić in Hagen, Germany. Professor Veselić studied mathematics at the University of Zagreb, where he started his teaching and scientific career.

Professors Drmač and Veselić are among co-organisers of the well known workshop series IWASEP which is particularly consecrated to highly reliable computing of the eigenvalue and singular value problems.

Our sincere congratulations to the recipients of the award and lots of success in future work!

Emeritierter Mathematiker vermittelt große Bücherspende nach Kroatien

In der Universitätsbibliothek werden sie nicht mehr gebraucht, aber ins Altpapier kommen deshalb sie noch lange nicht: Ältere Bücher aus den Beständen der Mathematik und der Informatik treten dieser Tage eine Reise nach Kroatien an. Sie werden dort die Ausstattung der Universitätsbibliotheken in Ossijek und in Rijeka vervollständigen.

Die Mitarbeiterinnen und Mitarbeiter der Hagener Universitätsbibliothek haben hunderte Bücher aus den Beständen aussortiert, von denen inzwischen beispielsweise neuere Auflagen angeschafft wurden oder die nicht mehr nachgefragt werden. Etwa, weil das Studienangebot der FernUniversität sich verändert hat und zudem die Literaturlisten einiger Kurse andere Schwerpunkte setzen.

Für die Altpapiertonne sind diese Bücher allerdings viel zu schade. Stattdessen nahm der emeritierte Mathematiker Prof. Dr. Krešimir Veselić sie Stück für Stück in Augenschein: Veselić organisiert eine Bücherspende in großem Stil. Der ehemalige Leiter des Lehrgebiets Mathematische Physik an der FernUniversität unterhält enge Beziehungen zu den Universitäten seines Geburtslands Kroatien. Nicht zuletzt haben einige kroatische Doktoranden seines Lehrgebiets heute dort Professuren inne.

Die Universitäten Kroatiens befinden sich immer noch in der Aufbauphase; Veselić engagiert sich hier in vielfältiger Weise. In schwierigen Zeiten holte er junge kroatische Mathematiker nach Hagen, heute trägt er unter anderem mit den Hagener Büchern zum Aufbau bei. In Rijeka beispielsweise wird das Institut für Mathematik zur Fakultät ausgebaut. Dort soll natürlich auch die zugehörige mathematische Bibliothek entstehen, zu der die Spende aus Hagen ihren Teil beiträgt. In Ossijek wächst zudem das Fach Informatik deutlich. Mathematiker Veselić ließ sich deshalb beraten, nach welchen Kriterien er informatische Fachliteratur auswählen sollte: Diese Fachbücher veralten enorm schnell; fündig geworden ist Veselić trotzdem.

Zusammengekommen sind trotz seiner strengen Auswahl gut und gern 25 Regalmeter Bücher, die jetzt mit dem Zug nach Kroatien verschickt werden. Bibliotheksleiterin Karin Michalke freut sich, „auf diese Weise wertvolle Aufbauhilfe zu leisten“ und sicherte gern die Unterstützung der Hagener Bibliothek zu. So müssen beispielsweise alle dort aussortierten Bücher entsprechend gekennzeichnet und in einem Begleitschreiben als Spende deklariert werden - ein wichtiges Detail, damit für die Aufbauhilfe nicht auch noch Zollgebühren fällig werden.

Niže možete poslušati njihove izvedbe dvaju starih hrvatskih napjeva.


Bog se rodi v Vitliomi [mp3]

Bog se rodi Vitliomi,
Đavlju silu tada slomi.
Gradu ime tako biše,
Kako prorok Božji piše.

Tu pastiri blizu stahu
Pri ovčicah i ne spahu.
Svetlost Božja na njih pride,
Pred kom noćna tma otide.

O Isuse, Bože blagi,
Bogu Ocu vele dragi,
Ti nam pute k sebi kaži,
Naše duše rajem blaži. Amen.

Napjev je glazbeno obradio prof. Ivan Golčić. Tekst je iz 14. stoljeća, zapisan u najstarijoj poznatoj hrvatskoj pjesmarici, tzv. Pariškom zborniku iz godine 1380. Ta knjiga pisana hrvatskom glagoljicom čuva se u Nacionalnoj knjižnici (Bibliothéque Nationale) u Parizu.

Sljedeći stari hrvatski napjev je iz Bosne:


Zdravo tijelo Isusovo [mp3]

Zdravo tijelo Isusovo, na oltaru posvećeno,
Zdravo tijelo Isusovo, na Svetim Duhom upućeno,
Zdravo tijelo Isusovo, od djevice porođeno,
Zdravo tijelo Isusovo, u jaslice položeno,
Zdravo tijelo Isusovo, velegorko izmučeno,
Zdravo tijelo Isusovo, za nas na križ pribijeno,
Zdravo tijelo Isusovo, mrtvo u grob sahranjeno,
Zdravo tijelo Isusovo, treći danak uskrsnulo
Zdravo tijelo Isusovo, po svem svijetu proslavljeno
O Isuse, budi hvaljen posve vike vikom. Amen.

Zahvaljujem prof.dr. Krešimiru Veseliću na tekstovima i tonskim zapisima pjesama kao i prof. Ivanu Golčiću za dozvolu korištenja njegove obrade.

Professor Krešimir Veselić lecturing at the City Library in Zadar, Croatia: On the Life and Work of blessed Edith Stein.


Krešimir Veselić: O životu i radu Edith Stein

Dr. Krešimir Veselić, profesor emeritus matematičke fizike na Fernuniversitaet Hagen i dopisni član HAZU, u četvrtak je održao predavanje o Edith Stein u Multimedijalnoj dvorani Gradske knjižnice Zadar.

Dr. Veselić predstavio je život i rad ove Židovke i katolkinje, filozofa, angažirane intelektualke, redovnice karmelićanke, žrtve nacističkog terora i svetice Katoličke Crkve.

Blažena Edith Stein u svijetu, a u redu sestra Terezija Benedikta od Križa, rođena je u židovskoj obitelji 12. listopada 1891. u Breslauu.

Odgojena je prema strogoj tradiciji židovske religije, no već u trinaestoj godini izgubila je vjeru.

1911. počela je slušati predavanja iz germanistike i filozofije na sveučilištu rodnog mjesta, a posebno ju je zanimala filozofija: 1913. prešla je na sveučilište u Göttingen da sluša Husserla, začetnika fenomenologije.

U kolovozu 1916. Edith polaže doktorski ispit iz filozofije, i iste godine postaje Husserlova asistentica na sveučilištu u Freiburgu.

U međuvremenu rat uzima stotine tisuća žrtava. Među žrtvama bio je i njen prijatelj Adolf Reinach koji ju je i upoznao s Husserlom. Očarana autobiografijom sv. Terezije Avilske, proučava Katolički katekizam i Rimski misal.

1922. primila je sveto krštenje i uzela ime Tereza - Hedviga. Nakon obraćenja Edith Stein imala je samo jednu želju: po uzoru sv. Terezije posvetiti se potpuno Bogu u karmelu.

Osam godina živjela je u samostanu dominikanki skromno i tiho kao redovnica. Primila se docenture na Njemačkom institutu za znanstvenu pedagogiju u Münsteru. U siječnju 1933. Hitler je postao kancelar Reicha, te počinju progoni Židova. Novo zakonodavstvo isključivalo je sve nearijevce iz javnih službi. Zato je Edith morala napustiti docenturu.



Stupanje u karmel bilo je za Edith silazak sa slavne životne karijere u dubine neznatnosti. Njezina 'Znanost križa' nije samo teoretska studija o sv. Ivanu od Križa, nego i povijest njezine duše koja u misteriju Križa vidi duboki i tajanstveni smisao.

Njezina autobiografija nije dovršena, i nije se znalo što se dogodilo s njom. Tek kasnije ustanovljeno je da je, zajedno sa sestrom Rozom preminula u Auschwitzu 9. kolovoza 1942. Sveti Otac Ivan Pavao II. proglasio ju je blaženom u Kölnu, 1. svibnja 1987. godine.

Dr. Veselić u svoje predavanje uključio je brojne izvore, zapise i pisma, dojmove onih koji su s njom živjeli i radili, kao i njezina pisma i dijelove značajnih tekstova.

Znamenita karmelićanka Edit Stein svojim je životnim putom - od ortodoksnog židovstva, preko ateizma do redovničkog života do mučeničke smrti u nacističkom logoru - posvjedočila neizmjernu ljubav prema Bogu. 'Ona je svjetionik i upitnik, koji nas potiče na preispitivanje vlastitog stava prema vječnim stvarnostima', zaključio je dr. Veselić.
