## Biographical infoMladen Bestvina is a three-time medalist at the International Mathematical Olympiad (two silver medals in 1976 and 1978 and a bronze medal in 1977). Bestvina gave an Invited Address at the International Congress of Mathematicians in Beijing in 2002. Bestvina served as an Editorial Board member for the Transactions of the American Mathematical Society. ## Mathematical contributionsA 1988 monograph of Bestvina In a 1992 paper Bestvina and Feighn obtained a Bestvina and Feighn also gave the first published treatment of Rips' theory of stable group actions on A 1992 paper of Bestvina and Handel introduced the notion of a train track map for representing elements of Out( α is free of rank at most n. Since then train tracks became a standard tool in the study of algebraic, geometric and dynamical properties of automorphisms of free groups and of subgroups of Out(F). Examples of applications of train tracks include: a theorem of Brinkmann_{n}^{} proving that for an automorphism α of F the mapping torus group of _{n}α is word-hyperbolic if and only if α has no periodic conjugacy classes; a theorem of Bridson and Groves^{} that for every automorphism α of F the mapping torus group of _{n}α satisfies a quadratic isoperimetric inequality; a proof of algorithmic solvability of the conjugacy problem for free-by-cyclic groups;^{[30]} and others.Bestvina, Feighn and Handel later proved that the group Out( ^{}settling a long-standing open problem.In a 1997 paper |

Mladen Bestvina: Distinguished Professor at the University of UTAH Congratulations to Mladen Bestvina, who was named one of five new Distinguished Professors at the University of Utah in 2004. Mladen joined our faculty in 1993 after an associate professorship at UCLA and visiting positions at MSRI, IHES, IAS in Princeton and Berkeley. Mladen completed his Ph.D. at the University of Tennessee under the direction of J.Walsh. He is a leading authority in geometric topology and geometric group theory. Maladen is editor of eight mathematics journals, has organized numerous special semesters and conferences in geometric group theory and topology and has directed eleven Ph.D. students, seven at Utah. Mladen is a terrific lecturer who received the department’s Faculty Undergraduate Teaching Award in 2006. Mladen views algebraic problems geometrically by studying actions of infinite groups on topological spaces. He has made many fundamental contributions to the field of geometric group theory. Among them are Bestvina-Brady Morse theory for studying the finiteness properties of groups, the Bestvina-Handel algorithm for studying dynamical properties of homotopy equivalences of graphs or surfaces, and the Bestvina normal form for Artin groups.

Professor Bestvina was born near the city of Osijek, on the NW part of Croatia. He has published a paper in Mathematica communications, a professional journal issued by the Math Society of the Osijek University, where he serves as a member of the editorial board. See Mladen Bestvina: PL Morse Theory. The paper is based on his lecture delivered in 2008 at the Fourth Croatian Mathematical Congress 2008 in Osijek, where professor Bestvina was a member of the scientific committee. |
