The existence and Ulam stability of solutions of a discrete nonlinear fractional boundary value problem are studied. The existence results are established based on Schaefer fixed point theorem and inequality analysis technique. Meanwhile
new criteria for Ulam stability of solutions to the nonlinear fractional difference equation are provided and examples are presented to illustrate the effectiveness of the main results.
