Recent results on fractional Lyapunov-type inequalities: A survey

This survey paper complements to our previous review papers on Lyapunov-type inequalities and contains some of the most recent results on these inequalities for fractional boundary value problems involving a variety of fractional derivative operators and boundary conditions.In precise terms, we have included the results related to Riemann-Liouville, Caputo, mixed Riemann-Liouville and Caputo, Riesz-Caputo, -Caputo, Hadamard, Katugampola, Hilfer, -Hilfer, proportional, variable order Hadamard, partial, systems of Riemann-Liouville, bi-ordinal Hilfer-Katugampola, and -Hilfer fractional derivative operators.The Lyapunov-type inequalities for discrete fractional boundary value problems are also presented.
