In this article we derive representations of Hecke operators for vector valued period functions for the congruence subgroups $Γ_0(n)$. For this we use an integral transform from the space of vector valued cusp forms to the space of vector valued period functions.v2: corrected version, submitted to Journal of Number, 29 pages, 1 figureNumber Theory11F25, 11F67text
