In this paper, we address the problem of vectorization of binary images on irregular isothetic grids. The representation of graphical elements by lines is common in document analys...
We determine set-theoretic defining equations for the variety Dualk,d,N P(Sd CN ) of hypersurfaces of degree d in CN that have dual variety of dimension at most k. We apply these ...

In this primarily expository article, I describe geometric approaches to variants of P v. NP, present several results that illustrate the role of group actions in complexity theory...
