The 212th meeting of Omsk Algebraic Online Webinar will be held on February 4

The Omsk Algebraic Online Webinar meeting #212 will take place on February 4 at 18:00 (Omsk time), 19:00 (Novosibirsk time), 07:00 (New York time), 15:00 (Moscow time).

Arkady Tsurkov (Federal University of Rio Grande do Norte (UFRN), Brazil) will present his talk "IBN-varieties of algebras".
The concept of a variety with IBN (invariant basic number) property first appeared in the ring theory. But we can define this concept for an arbitrary variety of universal algebras with an arbitrary signature. The proof of the IBN propriety of some variety is very important in universal algebraic geometry. This is a milestone in the study of the relation between geometric and automorphic equivalences of algebras of this variety. We prove very simple but very useful for the study of IBN properties of different varieties theorems. We will consider some applications of these theorems. We will consider many-sorted universal algebras as well as one-sorted. So, all concepts and all results will be generalized for the many-sorted case.
