The F-pure threshold of a determinantal ideal

The F-pure threshold of a determinantal ideal

The F -pure threshold is a numerical invariant of prime characteristic singularities, that constitutes an analogue of the log canonical thresholds in characteristic zero. We compute the F -pure thresholds of determinantal ideals, i.e., of ideals generated by the minors of a generic matrix.
