چکیده

We define self-adjoint extensions of the Hodge Laplacian on Lipschitz domains in Riemannian manifolds, corresponding to either the absolute or the relative boundary condition, and examine regularity properties of these operators’ domains and form domains. We obtain results valid for general Lipschitz domains, and stronger results for a special class of “almost convex” domains, which apply to domains with corners.

Green’s Identity in Curvilinear Polygons

For PDE examples illuminating the feedback (Redheffer product) theory of conservative boundary control systems, we need to verify conservativity of various hyperbolic PDE’s in domains Ω that have Lipschitz boundaries. A properly rigged version of Green’s Identity is then required on such domains where technical assumptions on functions at the corners of ∂Ω cannot be tolerated; such as present i...

Uniqueness for Two-Dimensional Incompressible Ideal Flow on Singular Domains

We prove uniqueness of the weak solution of the Euler equations for compactly supported, single signed and bounded initial vorticity in simply connected planar domains with corners forming angles larger than π/2. In this type of domain, the velocity is not log-lipschitz and does not belong to W 1,p for all p, which is the standard regularity for the Yudovich’s arguments. Thanks to the explicit ...

We study the Robin Laplacian in a domain with two corners of the same opening, and we calculate the asymptotics of the two lowest eigenvalues as the distance between the corners increases to infinity.

For a compact manifold with boundary X we introduce the n-fold scattering stretched product Xn sc which is a compact manifold with corners for each n, coinciding with the previously known cases for n = 2, 3. It is constructed by iterated blow up of boundary faces and boundary faces of multi-diagonals in Xn. The resulting space is shown to map smoothly, by a b-fibration, covering the usual proje...

On Optimal Estimates for the Laplace-Leray Commutator in Planar Domains with Corners

For smooth domains, Liu et al. (Comm. Pure Appl. Math. 60: 1443-1487, 2007) used optimal estimates for the commutator of the Laplacian and the Leray projection operator to establish well-posedness of an extended Navier-Stokes dynamics. In their work, the pressure is not determined by incompressibility, but rather by a certain formula involving the Laplace-Leray commutator. A key estimate of Liu...
