Venerdi' 8 Luglio 2011 alle ore 12.00 in aula 2AB45 il dott. Pablo Spiga (Milano Bicocca e Western Australia) terra' una conferenza dal titolo "A walk through primitive, quasiprimitive and semiprimitive groups: from a conjecture of Weiss to a conjecture of Babai-Seress".
In this talk we present some recent results (and a conjecture) on the subdegrees of a finite primitive permutation group. Some of the tools used in this area come from algebraic graph theory and these lead us to introduce a conjecture of Richard Weiss. We present the main ingredients of the recent solution of the Weiss conjecture for groups of bounded Lie rank and we show how these ingredients also apply to a conjecture of Babai and Seress.
