# Certain group dynamical systems induced by Hecke algebras

Ilwoo Cho

Abstract. In this paper, we study dynamical systems induced by a certain group $$\mathfrak{T}_{N}^{K}$$ embedded in the Hecke algebra $$\mathcal{H}(G_{p})$$ induced by the generalized linear group $$G_{p} = GL_{2}(\mathbb{Q}_{p})$$ over the $$p$$-adic number fields $$\mathbb{Q}_{p}$$ for a fixed prime $$p$$. We study fundamental properties of such dynamical systems and the corresponding crossed product algebras in terms of free probability on the Hecke algebra $$\mathcal{H}(G_{p})$$.

Keywords: free probability, free moments, free cumulants, Hecke algebra, normal Hecke subalgebra, free probability spaces, representations, operators, Hilbert spaces, dynamical systems, crossed product algebras.
