V. M. Buchstaber (Moscow, Russia)
n-valued groups

In 1971, V. M. Buchstaber and S.P. Novikov proposed a construction motivated by the theory of characteristic classes of quaternion vector bundles. This construction describes a multiplication in which the product of any pair of points is a multiset of n points. An axiomatic definition of n-valued groups, the results of their algebraic theory, and topological applications were obtained in a subsequent series of works by V. M. Buchstaber. Currently, the theory of n-valued (formal, finite, discrete, topological, and algebro-geometric) groups and their applications in various areas of mathematics and mathematical physics are being developed by a number of authors; The talk will present problems from various areas of mathematics, in the solution of which the results of the theory of n-valued groups played an important role.
