This chapter gives a partial account of the situation of Plateau's problem on the existence and regularity of soap films with a given boundary. It starts with a description of some of the most celebrated solutions of Plateau's problem, followed by a description of a few easy examples. The chapter then returns to the modeling problem and mentions a few additional ways to state a Plateau problem. It briefly describes the known local regularity properties of the Almgren minimal sets, and why we would like to extend some of these regularity results to sliding minimal sets, all the way to the boundary. At the same time, the chapter considers why these solutions are not always entirely satisfactory. Finally, the chapter explains why the regularity results for sliding Almgren minimal sets also apply to solutions of the Reifenberg and size minimization problems described earlier in the chapter.

In this paper we present a simpler proof of a result of Lewis concerning the continuity of weak solutions to the two-dimensional thermistor problem in the case where the temperature can blow up in a region with non-empty interior. Some other regularity properties are also discussed.

AbstractWe study local regularity properties of linear, non-uniformly parabolic finite-difference operators in divergence form related to the random conductance model on $$\mathbb Z^d$$ Z d . In particular, we provide an oscillation decay assuming only certain summability properties of the conductances and their inverse, thus improving recent results in that direction. As an application, we provide a local limit theorem for the random walk in a random degenerate and unbounded environment.

<p style='text-indent:20px;'>The main purpose of this paper is to study local regularity properties of the fourth-order nonlinear Schrödinger equations on the half line. We prove the local existence, uniqueness, and continuous dependence on initial data in low regularity Sobolev spaces. We also obtain the nonlinear smoothing property: the nonlinear part of the solution on the half line is smoother than the initial data.</p>
