We introduce the generalized convex function on fractal sets Rα (0<α≤1) of real line numbers and study the properties of the generalized convex function. Based on these properties, we establish the generalized Jensen's inequality and generalized Hermite-Hadamard's inequality. Furthermore, some applications are given.

Let l is an element of N and A = (A(1),..., A(l)) and f = (f(1) , . . ., f(l)) finite collections of functions, where every function Ai has derivatives of order m(i) and, f(1) , ..., f(l) is an element of L-e(infinity)(R-n). Let x is not an element of boolean AND(l)(i=1)Suppf(i). The generalized higher commutator generated by the multilinear fracti...
