Remarks on Landau-Siegel zeros

Number Theory 2025-12-09 v2

Abstract

For certain families of LL-functions, we prove that if each LL-function in the family has only real zeros in a fixed yet arbitrarily small neighborhood of s=1s=1, then one may considerably improve upon the known results on Landau-Siegel zeros. Sarnak and the third author proved a similar result under much more restrictive hypotheses.
