A Galvin-Hajnal theorem for generalized cardinal characteristics

Published 14 Feb 2022 in math.LO | (2202.06655v2)

Abstract: We prove that a variety of generalized cardinal characteristics, including meeting numbers, the reaping number, and the dominating number, satisfy an analogue of the Galvin-Hajnal theorem, and hence also of Silver's theorem, at singular cardinals of uncountable cofinality.
