Abstract: Polarization is a technique in algebra which provides combinatorial tools to study algebraic invariants of monomial ideals. Depolarization of a square free monomial ideal is a monomial ideal whose polarization is the original ideal. We develop a new depolarization method using special hyper graph coloring. In this talk, we briefly introduce the distraction, ideal of subspace arrangement, and related depolarization problems. Also we introduce our new hyper graph technique and related open problems.
