Hermite–Hadamard inequality is a double that provides an upper and lower bounds of the mean (integral) convex function over certain interval. Moreover, convexity can be characterized by each two sides this inequality. On other hand, it well known twice differentiable convex, if only admits nonnegative second-order derivative. In paper, we obtain characterization class functions (including funct...

It is a familiar fact that inequalities have become very popular method using fractional integrals, and this has been the driving force behind many studies in recent years. Many forms of inequality studied, resulting introduction new trend theory. The aim paper to use fuzzy order relation introduce various types inequalities. On interval space, defined level by level. With help relation, firstl...
