## Existence of solutions for some boundary value problems of fractional $$p$$-Laplacian equation at resonance.(English)Zbl 1283.34004

The paper is concerned with the existence of solutions of the following two boundary value problems for $$p$$-Laplacian differential equations at resonance: $D_{0^+}^\beta\phi_p(D_{0^+}^\alpha x(t))=f(t,x(t),D_{0^+}^\alpha x(t)),\quad t\in[0,1],$
$x(0)=0,\quad D_{0^+}^\alpha x(0)=D_{0^+}^\alpha x(1);$ and $D_{0^+}^\beta\phi_p(D_{0^+}^\alpha x(t))=f(t,x(t),D_{0^+}^\alpha x(t)),\quad t\in[0,1],$
$x(1)=0,\quad D_{0^+}^\alpha x(0)=D_{0^+}^\alpha x(1).$ The main tool is the coincidence degree theory. An example is given as an application of their results.
