Семинар “Алгебра и логика”
ZoomНа 18 юни 2021 г. (петък) от 13:00 часа ще се проведе дистанционно заседание на семинара "Алгебра и логика". Доклад на тема Primary decompositions of unital locally matrix algebras and Steinitz numbers ще изнесе Bogdana Oliynik (National University of Kyiv-Mohyla Academy, Kyiv, Ukraine). Резюме. Let F be a ground field. An F-algebra A with unit 1 is said to be a locally matrix algebra if an arbitrary finite collection of elements a1, . . . , as from A lies in a subalgebra B with 1 of the algebra A, and B is isomorphic to a matrix algebra Mn(F), n ≥. We assign a Steinitz number n(A) to an arbitrary unital locally matrix algebra A. In this talk, we outline the construction of a [...]
