Abstract: We derive integral representations for the Catalan numbers C(n), shifted Catalan numbers C(n+p), and the numbers n!*C(n) and C(n)*B(n), where B(n) are the Bell numbers, for n=0,1... Our method is to use inverse Mellin transform. All these numbers are power moments of positive functions, and their representations turn out to be unique.
