Abstract
This note is concerned with some inequalities involving the function and its Caputo‐type Erdélyi–Kober fractional derivative. Namely, we establish integral inequalities of Poincaré, Sobolev, and Hilbert–Pachpatte types, with respect to the right‐hand sided Caputo‐type modification of the Erdélyi–Kober fractional derivative. The obtained inequalities are useful in analyzing fractional differential equations, in particular, in obtaining various estimate for the solutions.
