The main objective of present investigation is to obtain some Minkowski-type
fractional integral inequalities using generalised proportional Hadamard
fractional integral operators which is introduced by Rahman et al. in the
paper (Certain inequalities via generalized proportional Hadamard fractional
integral operators), Advances in Differential Equations, 2019, 454(2019). In
addition, we establish some other fractional integral inequalities for
positive and continuous functions.
