The character of the Weil representation of a finite abelian group of odd order

Frieder Ladisch

Let be a finite abelian group of odd order, equipped with a non-degenerate, alternating form . We give closed formulas for the cha…

Finding Supercharacter Theories on Character Tables

Frieder Ladisch

We describe an easy way how to find supercharacter theories for a finite group, if its character table is known. Namely, we show how an arbitrary partition of the conjugacy classes…

Character correspondences induced by magic representations

Frieder Ladisch

Let G be a finite group, K a normal subgroup of G and H a subgroup such that G = HK, and set L = H \cap K. Suppose θ\in Irr K and ϕ\in Irr L, and ϕ occurs in θ_L with multiplicity…
