I’m a mathematician interested in algebraic and geometric topology, as well as abstract algebra and global analysis. At the beginning of 2021, I retired from the Adam Mickiewicz University in Poznań, Poland. I’m still keeping a part time job here at the university in Poznań, where I teach and help students to write their Master and PhD Thesis.

My favorite hobby is reading of popular books about science in general, and mathematics in particular. I love to listen to classical music and all types of jazz.

*“The undeniable power of algebraic topology would alone command a leading place **in mathematics; but it has great beauty too, in organizing intuitively different structures **which defied earlier purely analytic or geometric approaches. It has also a leading **place in physics, for its success in organizing the most fundamental physical theories*.”

A broad consensus exists that a basic knowledge of algebraic topology is indispensable in modern mathematical student’s education. The education should include also some aspects of geometric topology understood in the restrictive sense where the focus is on the study of manifolds, central objects of interest in geometry, topology, and global analysis. Knots, links, and braids are especially intriguing objects in geometric topology, and some theoretical backgroud regarding these objects is advisable as well.
