The sparsity of character tables over finite reductive groups and its additive analogue
GyeongHyeon Nam, Anna Puskás
We consider the proportion of zero entries in the character table of a sequence of reductive groups over a finite field. We prove an asymptotic lower bound when the reductive group…

Counting points on generic character varieties
Masoud Kamgarpour, GyeongHyeon Nam, Bailey Whitbread +1
We count points on character varieties associated with punctured surfaces and regular semisimple generic conjugacy classes in reductive groups. We find that the number of points ar…
