Dr. Mervan Pašić, professor of Mathematics at the University of Zagreb, visited Japan from November 1122 2009 upon the invitation of Japanese mathematicians: Yuki Naito, Hiroyuki Usami, Tetsutaro Shibata and Jitsuro Sugie. He delivered an invited lecture at the University of Hiroshima and a plenary lecture at the University of Kyoto. The cities of Kyoto and Zagreb are twinned since 1972. 
Dr. Mervan Pašić visited Japan from November 1122 2009, upon the invitation of two Japanese mathematicians: Yuki Naito (Eshime University) and Hiroyuki Usami (Hiroshima University). He had the honour to deliver an invited lecture at the ''International Workshop on Qualitative Theory of ODE's in Hiroshima 2009'' [ODE = Ordinary Differential Equations], organized at the Hiroshima University. The title of his talk was Fractal oscillations: details, closed and open problems. We stress here that Mervan Pašić, professor of Mathematics at the University of Zagreb, layed down the foundations for this very interesting theory. After Hiroshima he visited the Universtiy of Kyoto from November 1722 2009 upon the invitation of another two Japanese professors: Tetsutaro Shibata (Hiroshima University) and Jitsuro Sugie (Shimane University). In Kyoto he had an exceptional honour to deliver a plenary (one hour) talk at the ''RIMS Conference: New Developments of Functional Equations in Mathematical Analysis'', held at the Faculty of Science Kyoto University [RIMS = Research in Mathematical Sciences]. The subject of his talk was Rectifiable, unrectifiable and fractal oscillations in differential equations'. He had fruitful discussions with Japanese mathematicians, and his visit was in fact a start of the collaboration of the University of Zagreb and the Universities of Hiroshima and Kyoto in the field of Mathematics. All the photos on which Dr. Mervan Pašić is not present were taken by himself. 
Here we provide a few personal remarks by Dr. Mervan Pašić after his return from Japan to Croatia:

Professor Mervan Pašić is the first Croatian mathematician to collaborate with Japanese mathematicians in the field of Differential Equations. However he is not the first Croatian mathematician to have contacts with Japan. Academician Sibe Mardešić collaborated with Japanese mathematicians in the field of Topology (and in particular in Shape Theory). In 1981 he spent two months in Japan upon the invitation of the University of Tsukuba. Goran Muić, professor at the University of Zagreb, working in the field of Representation Theory of Groups, had the honour to deliver two invited lectures at the University of Kyoto in 2003. And probably the most interesting Croatian mathematician related to Japan is academician Vladimir Devidé. His professional work was in the field of Mathematical Logic. He is widely known, also outside of Croatia, for his tireless and very fruitful work in popularizing Japanese culture, and in particular Japanese poetry. Croatia  Japan
