MATH Seminar (1): “Bimodules of Spaces?” Redi Haderi, SA-141, 1:40PM October 14 (EN)

Dear Colleagues and Students,
You are cordially invited to the Topology Seminar organized by the Department of Mathematics.

Speaker: Redi Haderi (Bilkent)

“Bimodules of spaces?”

Abstract: If X and Y are algebraic objects like monoids, groups, rings etc., we define bimodules to carry a left action from X and a right action for Y, and typically organize them in a double category. We will entertain the idea of a bimodule in the case where X and Y are simplicial sets (and general spaces or CW-complexes). We will draw the analogy from the special case of categories, where bimodules have various interpretations and homotopical meaning. In particular representable bimodules are mapping cylinders for categories. Because of the lack of algebraic structure bimodules of spaces do not tensor. Time permitting we will discuss a remedy for this issue.
