The rank evolution of block bidiagonal matrices over finite fields

András Mészáros

We investigate uniform random block lower bidiagonal matrices over the finite field $F_{q}$ , and prove that their rank undergoes a phase transition. First, we consider block…

A phase transition for the cokernels of random band matrices over the p-adic integers

András Mészáros

Let $B_{n}$ be an $n \times n$ Haar-uniform band matrix over $Z_{p}$ with band width $w_{n}$ . We prove that $cok (B_{n})$ has Cohen-Lenstra limiting distrib…
