For any function F(x) having a Taylor expansion we solve the boson normal ordering problem for , with r, s positive integers, , i.e., we provide exact and explicit expressions for its normal form = , where in all a's are to the right. The solution involves integer sequences of numbers which, for , are generalizations of the conventional Bell and Stirling numbers whose values they assume for . A complete theory of such generalized combinatorial numbers is given including closed-form expressions (extended Dobinski-type formulas), recursion relations and generating functions. These last are special expectation values in boson coherent states.
