Popis: We prove that the killing rate of certain degree-lowering “recursion operators” on a polynomial algebra over a finite field grows slower than linearly in the degree of the polynomial attacked. We also explain the motivating application: obtaining a lower bound for the Krull dimension of a local component of a big [math] Hecke algebra in the genus-zero case. We sketch the application for [math] and [math] in level one. The case [math] was first established in by Nicolas and Serre in 2012 using different methods.
