Polynomial evaluations
We briefly account for various notions of evaluations of polynomials in noncommutative settings. We then concentrate on different types of Ore extensions, with one or more variables. Some presented results generalize classical results and open …

Locally matrix and locally standard algebras and Steinitz numbers
In this talk, based on joint papers with Oksana Bezushchak, we consider parametrization of locally matrix and locally standard algebras by Steinitz numbers. Glimm showed that every countable-dimensional unital locally matrix algebra is uniquely determined …

Self-distributive structures and reflections to set-theoretic solutions of the Yang–Baxter equation
The Yang–Baxter equation (YBE) is a fundamental equation of mathematical physics that has been extensively studied in the last few years. Alongside it, the reflection equation serves as a significant tool in the theory of …

Non-fixing graphs of skew braces
In this talk, based on joint work with Silvia Properzi, we recall some core concepts of skew braces. Next, we introduce the non-fixing graph of a skew brace, inspired by the conjugacy class graph as …

O radykałach pierścieni skośnych wielomianów
Given a ring R, radicals of the polynomial ring R[x], and even of the skew polynomial ring R[x; σ] skewed by an automorphism σ on R, have been studied and described for many different radicals. …

Cabling techniques for bijective solutions of the Yang–Baxter equation
In this talk, we introduce a definition of cabling for bijective non-degenerate set-theoretic solutions to the Yang–Baxter equation, with a focus on indecomposability. We examine fundamental differences between involutive and non-involutive solutions, particularly that involutive …

Algebry barycentryczne i współrzędne barycentryczne (Barycentric algebras and barycentric coordinates)
Barycentric algebras were introduced in the nineteen-forties for the axiomatization of real convex sets, presented algebraically with binary operations given by weighted means, the weights taken from the (open) unit interval in the real numbers. …
