  The main objective of present investigation 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), 2019:454. In addition,
we establish some other fractional integral inequalities for positive and
continuous functions.
