Dmitriy Konstantinovich Potapov · Differential Equations · 2012
We consider the problem of the existence of solutions of the spectral problem for higher-order equations of elliptic type with discontinuous nonlinearities. By using the variational method, we prove theorems on the number of semiregular solutions for the problems in question.
