Starting from the famous Schauder fixed-point theorem, we presentsome Lefschetz-like and Nielsen-like generalizations for certainadmissible (multivalued) self-maps on metric ANR-spaces. Thesefixed-point principles are applied for obtaining the existence andmultiplicity results for boundary value problems.
