The next meeting of the Algebra and Logic Seminar will be held on February 22, 2019 (Friday) at 1:00 p.m. in Room 578 of the Institute of Mathematics and Informatics. A talk on NILPOTENT AND UNIPOTENT MATRICES OVER A FIELD WITH APPLICATIONS TO VON NEUMANN REGULAR RINGS AND FUNCTIONAL ANALYSIS will be delivered by Peter DANCHEV. Everybody is invited. Abstract Introduction: The question of whether or not the nilpotent square matrix is a linear combination of idempotent matrices is too long-standing and left-open yet. So, further results of this type would be of some interest and eventual importance. The goal of the present note is to promote such a kind of results with a possible application to the classical von Neumann regular rings and to the [...]

The next meeting of the Algebra and Logic Seminar will be held on November 30, 2018 (Friday) at 1:00 p.m. in Room 578 of the Institute of Mathematics and Informatics. A talk on DECOMPOSING NORMALIZED UNITS IN COMMUTATIVE MODULAR GROUP RINGS will be delivered by Peter DANCHEV. Everybody is invited. Abstract Introduction: Suppose G is an abelian p-group and F is a perfect field of characteristic p > 0. As usual, FG denotes the group algebra of G over F with group of normalized units V(FG) and augmentation ideal I(FG;G). For any ideal I of FG, we set I^n as the product of I written n times, where n is an arbitrary fixed natural number. The numerous decompositions of the normed group V(FG), in [...]
