The variety of nilpotent matrices is $F$ -regular

Jack Jeffries, Vaibhav Pandey, Anurag K. Singh

We give an elementary proof that the coordinate ring of the variety of nilpotent matrices is $F$ -regular; over an infinite field $K$ , this ring also arises as the nullcone for the…

Krishna Menon, Anurag Singh

The numbers we study in this paper are of the form $B_{n, p} (k)$ , which is the number of binary words of length $n$ that contain the word $p$ (as a subsequence) exactly $k$ times.…
