  A survey of results on Lyapunov-type inequalities for fractional differential
equations associated with a variety of boundary conditions is presented. This
includes Dirichlet, mixed, Robin, fractional, Sturm-Liouville, integral,
nonlocal, multi-point, anti-periodic, conjugate, right-focal and impulsive
conditions. Furthermore, our study includes Riemann-Liouville, Caputo,
Hadamard, Prabhakar, Hilfer and conformable type fractional derivatives.
Results for boundary value problems involving fractional $p$-Laplacian,
fractional operators with nonsingular Mittag-Leffler kernels, $q$-difference,
discrete, and impulsive equations, are also taken into account.
