Transfer systems for rank two elementary Abelian groups: characteristic functions and matchstick games
Linus Bao, Christy Hazel, Tia Karkos +6
We prove that Hill's characteristic function for transfer systems on a lattice surjects onto interior operators for . Moreover, the fibers of have unique maxima whic…
