On probabilistic generation of classical groups
at 1pm Friday 18th of November in MLR2
Abstract: Let G be a classical group and V be the underlying vector space of dimension 2n over a field of size q. Let ppd(q,n) denote a prime number which divides q^n-1 but not q^i-1 for i<n. Generically, such primes exist by Zsigmondy's result. We consider the elements of order ppd(n,q) which act irreducibly on a unique n-dimensional subspace and fix pointwise an n-dimensional subspace of V. We call these elements good elements. I will discuss the probabilistic generation of G by two random conjugate good elements and present an application in the computational group theory. This is a joint work with Cheryl Praeger and Akos Seress.
