Degenerate parabolic oblique derivative problem.
2004This paper deals with the Poincaré type problem for a second order linear uniformly parabolic operator \( P \) in the cylinder \( Q = \Omega \times [0,T) \). The boundary operator \( B \) is given by the oblique derivative with respect to a tangential vector field \( l \) defined on the lateral boundary \( S \).
