Guido Mislin

Guido Mislin (born April 13, 1941 in Basel) is a Swiss mathematician, academic and researcher. He is a Professor Emeritus of Mathematics at ETH Zurich. He is also associated with Ohio State University as a guest at Mathematics Department.

Mislin's main area of research is algebraic topology, focusing especially on questions regarding general localization theory, as they occur in the context of homotopy theory. He has also conducted research in the field of cohomology of groups and algebraic K-Theory of group rings. He has published over 90 research articles and several books including Localization of Nilpotent Groups and Spaces and Proper Group Actions and the Baum-Connes Conjecture.

Education Mislin completed his undergraduate studies and diploma in Mathematics in 1964 and received his Ph.D. in 1967 from ETH Zūrich. He then moved to U.S. and completed his post-doctoral studies from Cornell University and University of California, Berkeley.

Career Following his post-doctoral studies, Mislin was appointed as an assistant professor at the Ohio State University. Mislin is associated with ETH Zurich as a Professor Emeritus of Mathematics. He presented a theorem regarding constructing torsion classes in systemic manner, by using Chern classes of canonical representation. He discussed the results and also proved certain properties regarding the Chern classes of representations of cyclic groups.

Mislin authored a paper in 1990s regarding group homomorphisms inducing mod-p cohomology isomorphisms and highlighted the conditions on p in group theoretic terms for p to induce an H'Z/p-isomorphism. He applied the concept of satellites in order to define Tate cohomology groups for an arbitrary group G and G-module M.

Mislin focused on Bass conjecture and conducted a study to prove that the Bost Conjecture on the L1-assembly map for discrete groups implies the Bass Conjecture. He reformulated the weak Bass Conjecture as a comparison of ordinary and L2-Lefschetz numbers.

Mislin studied and extended the work conducted by several authors on theory of topological localization. He presented new results to the theory which were then applied to other studies. Mislin also presented a periodicity theorem and proved the various properties of homotopy groups of K-theory localization.
