on the space X = L 2 (0; T ; V ), where Q = ร(0; T ) and V = W 1; 2 0 (v; ) is a weighted Sobolev space, see Section 2. The degeneration is determined by a scalar function b(x) and a vector function v(x) = (v 1 (x); v 2 (x); : : : ; v N (x)) with positive components v i (x) in satisfying certain int
