Kaj Nyström: Boundary behaviour for non-negative solutions to non-linear and degenerate parabolic PDE:s

In this talk I will describe recent results concerning the boundary behavior of non-negative solutions to equations generalizing second order uniformly parabolic PDE:s in divergence form. Equations of interest include certain non-linear equations with linear growth, degenerate equations with ellipticity measured by A_p-weights as well as parabolic equations of p-parabolic type. The results are obtained in parts in collaboration with T. Kuusi, G. Mingione, H. Persson and O. Sande.
