MULTIPLICITY RESULTS FOR A CLASS OF NAVIER DOUBLY EIGENVALUE BOUNDARY VALUE SYSTEMS DRIVEN BY A (p1, . . . , pn)-BIHARMONIC OPERATOR
Armin Hadjian, Saleh Shakeri · 2015
Existence results of three weak solutions for a Navier doubly eigenvalue boundary value system involving the (p1;:::;pn)-biharmonic operator, under suitable assumptions, are established. The approach is fully based on Ricceri’s Variational Principle.
