On fractional discrete p-Laplacian equations via Clark’s theorem

作者:

Highlights:

• It is the first time in the literature to use a weaker condition of V (x) than coercivity to prove the existence of homoclinic solutions for discrete Laplacian problems.

• Different from [13, 14], we obtain more than two homoclinic solutions for problem (1) through quite different methods.

• We introduce a truncation function to deal with problem (1) with concave and convex nonlinearity so that the coercivity of the energy functional can be recovered.
