Lyapunov-Type Inequality for a Riemann-Liouville Type Fractional Boundary Value Problem with Robin Boundary Conditions

In this article we establish a Lyapunov-type inequality for two-point Riemann-Liouville fractional boundary value problems associated with well-posed Robin boundary conditions. To illustrate the applicability of established result, we deduce criterion for the nonexistence of real zeros of a Mittag-Leffler function.
