Uniformly semi-rational groups
Ãngel del RÃo, Marco Vergani
We introduce and study some families of groups whose irreducible characters take values on quadratic extensions of the rationals. We focus mostly on a generalization of inverse sem…

Uniformly semi-rational simple groups
Marco Vergani
A finite group is called uniformly semi-rational if there exists an integer such that the generators of every cyclic sugroup of lie in at most two c…
