On an invariant set in the heat conductivity problem with time lag. (English) Zbl 1304.35325
Summary: The problems of weak and strong invariance of a constant multivalued mapping with respect to the heat conductivity equation with time lag are studied. Sufficient conditions of weak and strong invariance of a given multivalued mapping are obtained.
