Title: Variance of the k-fold divisor function in arithmetic progressions for individual modulus

Abstract: We discuss some background and the proof of Corollary 1 in arXiv:2205.02354. This result is closely related to moments of Dirichlet L-functions and confirms a smoothed version of a recent conjecture of Keating–Rodgers–Roditty-Gershon–Rudnick-Soundararajan on the variance of the k-fold divisor function in arithmetic progressions to individual composite moduli, in a restricted range.
