Permutation representations of nonsplit extensions involving alternating groups
Robert M. Guralnick, Martin W. Liebeck
L. Babai has shown that a faithful permutation representation of a nonsplit extension of a group by an alternating group must have degree at least , an…

Rigid local systems and alternating groups
Robert M. Guralnick, Nicholas M. Katz, Pham Huu Tiep
In earlier work, Katz exhibited some very simple one parameter families of exponential sums which gave rigid local systems on the affine line in characteristic p whose geometric (a…

On isometry groups of self-adjoint traceless and skew-symmetric matrices
Marcell Gaál, Robert M. Guralnick
This note is concerned with isometries on the spaces of self-adjoint traceless matrices. We compute the group of isometries with respect to any unitary similarity invariant norm. T…
