Iyengar-Hilfer Generalized Fractional Inequalities

Here we present Iyengar type integral inequalities. At the univariate level they involve ψ -Hilfer left and right fractional derivatives. At the multivariate level they involve Hilfer left and right fractional derivatives, and they deal with radial and non-radial functions on the ball and spherical shell. All estimates are with respect to norms ∥ · ∥p, 1 ≤ p≤ ∞. At the end we provide an application
