Title: The variety of orthogonal frames
Abstract: Orthogonal frames are tuples of pairwise orthogonal vectors in a quadratic vector space. We study the variety of all orthogonal frames and its defining ideal, and discuss their algebraic, geometric and topological properties. We discuss applications to Lovász-Saks-Schrijver ideals of graphs. Joint work with Alessio Sammartano.
