Multiplicity theorems for the Dirichlet problem involving the p-Laplacian

Existence and multiplicity results for elliptic problems with Nonlinear Boundary Conditions and variable exponents

“…Ricceri's three critical points theorem is a powerful tool to study boundary problem of differential equation (see, for example, [1,3,4,5]). Particularly, Mihailescu [17] use three critical points theorem of Ricceri [19] study a particular p(x)-Laplacian equation.…”

Nontrivial Solutions for Dirichlet Boundary Value Systems with the(p1,…,pn)-Laplacian

“…Due to importance of second-order Dirichlet and Neumann problems in describing a large class of physic phenomena, many authors have studied the existence and multiplicity of solutions for such a problem; we refer the reader to [1][2][3][4][5][6][7][8][9][10][11][12][13] and references therein. Some authors also study the system case; see [14][15][16][17][18][19][20].…”
