Integrality of Averages of Roots of Unity and Perfect Isometries
Chatchawan Panraksa, Pornrat Ruengrot
We establish a criterion for the integrality of averages of roots of unity and apply it to settle a conjecture regarding the linearity of functions on . Specifically,…

Perfect Isometry Groups for Cyclic Groups of Prime Order
Pornrat Ruengrot
A perfect isometry is an important relation between blocks of finite groups as many information about blocks are preserved by it. If we consider the group of all perfect isometries…

A Note on Average of Roots of Unity
Chatchawan Panraksa, Pornrat Ruengrot
We consider the problem of characterizing all functions defined on the set of integers modulo with the property that an average of some th roots of unity determined by $…
