YOUNG SEMINAR: Derivation Radical Subspace arrangements

speaker: Max Wakefield (United States Naval Academy, Annapolis)

abstract: If a subspace arrangement contains a subspace of codimension higher than one then the associated logarithmic module of derivations is not free. In this lecture we discuss a possible generalization of freeness to subspace arrangements which we call derivation radical. We show that some special collections of subspaces of the braid arrangement are derivation radical. If time permits we will discuss how this definition relates to free hyperplane arrangements.
