Up and Down h-Pre-Invex Fuzzy-Number Valued Mappings and Some Certain Fuzzy Integral Inequalities

The objective of the current paper is to incorporate the new class and concepts of convexity and Hermite-Hadamard inequality with the fuzzy Riemann integral operators because almost all classical single-valued and interval-valued convex functions are special cases of fuzzy-number valued convex mappings. Therefore, a new class of nonconvex mapping in the fuzzy environment has been defined; up and down h-pre-invex fuzzy-number valued mappings (U.D h-pre-invex F-N center dot V center dot Ms). With the help of this newly defined class, some new versions of Hermite-Hadamard (HH) type inequalities have been also presented. Moreover, some related inequalities such as HH Fejer- and Pachpatte-type inequalities for U center dot D h-pre-invex F-N center dot V center dot Ms are also introduced. Some exceptional cases have been discussed, which can be seen as applications of the main results. We have provided some nontrivial examples. Finally, we also discuss some future scopes.
