ARGOMENTI: Seminari

Il prof. Nigel Boston, University of Wisconsin - Madison terra' un seminario giovedi 1 aprile, alle ore 11.30 in aula 1BC/45 dal titolo "Large Transitive Groups with Many Elements having Fixed Points".

-Abstract
We present a counterexample to a conjecture of Jones, arising out of number theory, by exhibiting a compatible sequence of transitive groups with degree $2^n$, order $2^(2^(n-1)+1)$ and at least $1/4$ of their elements having fixed points.
