Sufficient conditions on the existence of multiple solutions are obtained by using the critical point theory. Necessary conditions for a particular solution subject to pre-defined criteria are also investigated. Examples are given to illustrate the applications of the results as well. %Z Bibliogr.: p. 12-13. ; összefoglalás angol nyelven
