A Compact Trace Theorem for Domains with External Cusps
نویسنده
چکیده
This paper deals with the compact trace theorem in domains Ω ⊂ R 3 with external cusps. We show that if the power sharpness of the cusp is bellow a critical exponent, then the trace operator γ : H(Ω) → L(∂Ω) exists and it is compact.

Gauss Images of Hyperbolic Cusps with Convex Polyhedral Boundary François Fillastre and Ivan Izmestiev
We prove that a 3–dimensional hyperbolic cusp with convex polyhedral boundary is uniquely determined by its Gauss image. Furthermore, any spherical metric on the torus with cone singularities of negative curvature and all closed contractible geodesics of length greater than 2π is the metric of the Gauss image of some convex polyhedral cusp. This result is an analog of the Rivin-Hodgson theorem ...
متن کاملNonhomogeneous Neumann Problem for the Poisson Equation in Domains with an External Cusp
Abstract. In this work we analyze the existence and regularity of the solution of a nonhomogeneous Neumann problem for the Poisson equation in a plane domain Ω with an external cusp. In order to prove that there exists a unique solution in H(Ω) using the Lax-Milgram theorem we need to apply a trace theorem. Since Ω is not a Lipschitz domain, the standard trace theorem for H(Ω) does not apply, i...
متن کاملSolutions of the Divergence and Korn Inequalities on Domains with an External Cusp
This paper deals with solutions of the divergence for domains with external cusps. It is known that the classic results in standard Sobolev spaces, which are basic in the variational analysis of the Stokes equations, are not valid for this class of domains. For some bounded domains Ω ⊂ R presenting power type cusps of integer dimension m ≤ n−2, we prove the existence of solutions of the equatio...
متن کاملRationality Problems for K-theory and Chern-simons Invariants of Hyperbolic 3-manifolds
This paper makes certain observations regarding some conjectures of Milnor and Ramakrishnan in hyperbolic geometry and algebraic K-theory. As a consequence of our observations, we obtain new results and conjectures regarding the rationality and irrationality of Chern-Simons invariants of hyperbolic 3-manifolds. In this paper, by a hyperbolic 3-manifold, we shall mean a complete, oriented hyperb...
