Abstract

We study the total cut complexes and their Alexander duals. The homotopy type of these complexes is calculated for de ppth power of a cycle with at least 2rn2rn vertices where prp\leq r, solving part of a conjecture of Bayer, Denker, Milutinovi\'c, Rowlands, Sundaram and Xue. The homotopy type of the 22-total cut complex for any rrth power of a cycle with r3r\geq3 also is calculated, solving a conjecture of Chauhan, Shukla and Vinayak. We give some results about the connectivity. The homotopy type of the complexes for complete multipartite graph is determined. We also study the complexes of cartesian products of paths and of cartesian products of complete graphs for the total 22-cut complex.
