Abstract
We shall study the behaviour of solutions of the equation
at a point . Indeed we establish a necessary condition to the regularity of a boundary point of the cylindrical domain extending the analogous result from paper [13] to the degenerate case. The degeneration is given by weights (depending on the space variable) from a suitable Muchenhoupt class. It is important to note that the coefficients of the equation depend on time too.
