On a unified integral operator for φ-convex functions

초록

Integral operators have a very vital role in diverse fields of science and engineering. In this paper, we use phi-convex functions for unified integral operators to obtain their upper bounds and upper and lower bounds for symmetric phi-convex functions in the form of a Hadamard inequality. Also, for phi-convex functions, we obtain bounds of different known fractional and conformable fractional integrals. The results of this paper are applicable to convex functions.
