F-threshold of determinantal rings

  • Barbara Betti (MPI MiS, Leipzig)
G3 10 (Lecture hall)


In this talk we will introduce some notions for positive characteristic rings useful to detect singularities of the corresponding varieties. In particular we will focus on F-singularities of determinantal rings and, using a combinatorial approach, we establish a new upper bound for the F-threshold of rings generated by maximal minors and we compute the exact value in the case of 3×n and 4×n matrices.
