In a finite Coxeter group and with two given conjugacy classes of parabolic subgroups and , we count those parabolic subgroups of in that are full support,…

On enumerating factorizations in reflection groups
Theo Douvropoulos
We describe an approach, via Malle's permutation on the set of irreducible characters , that gives a uniform derivation of the Chapuy-Stump formula for the enume…

Simultaneous generic approximation by the iterates of the Cesaro operator
Theodosios Douvropoulos
We show that for the generic sequence (a) of elements in a subset A of a separable locally convex metrisable space V, the sequences [T^k(a)]_n, n=1,2,... are dense in the convex hu…
