Abstract. A beautiful geometric characterization of domains was established in the celebrate work of Norbert Wiener (1924) for the solvability of boundary value problem of harmonic functions.
In this talk, I will review some known results on Wiener's criterion for elliptic and parabolic equations. Estimates of modulus of continuity for solutions at the boundary will be given in terms of a Wiener-type integral, defined by a notion of capacity. In particular, some recent advances on such estimates for solutions to singular or degenerate parabolic equations will be reported.
