Simplifying the Weft Hierarchy
We give simple, self-contained proofs of the basic hardness results for the classes W[t] of the weft hierarchy. We extend these proofs to higher levels of the hierarchy and illuminate the distinctions among its classes. The anti-monotone collapse at W[\documentclass[12pt]{minimal} \usepackage{amsmat...
