Kohei Tanaka - Sectional Category for Maps of Finite Spaces

Explore the sectional category of maps between finite T_0 spaces (posets) from a combinatorial perspective in this 47-minute lecture. Delve into the computation of sectional category examples, focusing on the McCord map, weak homotopy equivalence on barycentric subdivision, and Fadell-Neuwirth fibration associated with finite spaces. Gain insights into applied algebraic topology as presented by Kohei Tanaka for the Applied Algebraic Topology Network.
