Accessible Domains in the Heisenberg Group
We study the problem of accessibility of boundary points for domains in the sub–Riemannian setting of the first Heisenberg group. A sufficient condition for accessibility is given. It is a Dini–type continuity condition for the horizontal gradient of the defining function. The sharpness of this condition is shown by examples.
متن کاملOn Conically Ordered Convex Programs
In this paper we study a special class of convex optimization problems called conically ordered convex programs (COCP), where the feasible region is given as the level set of a vector-valued nonlinear mapping, expressed as a nonnegative combination of convex functions. The nonnegativity of the vectors is defined using a pre-described conic ordering. The new model extends the ordinary convex pro...
متن کاملA Boundary Approximation Algorithm for Planar Domains
Suppose T is a triangulation T of R with edges E and vertices V, and suppose Ω is a bounded open subset of R. Let Vin = {v ∈ V : v ∈ Ω}. In this paper we will give an algorithm which uses Vin and nothing else to construct a finite disjointed family P of simple closed polygons whose union approximates, in a sense we shall make precise, the boundary ∂Ω of Ω. Of course we will need to assume somet...
متن کاملThe Martin Boundary in Non-lipschitz Domains
The Martin boundary with respect to the Laplacian and with respect to uniformly elliptic operators in divergence form can be identified with the Euclidean boundary in Cγ domains, where γ(x) = bx log log(1/x)/ log log log(1/x), b small. A counterexample shows that this result is very nearly sharp.
متن کاملRobin Boundary Value Problems on Arbitrary Domains
We develop a theory of generalised solutions for elliptic boundary value problems subject to Robin boundary conditions on arbitrary domains, which resembles in many ways that of the Dirichlet problem. In particular, we establish Lp-Lq-estimates which turn out to be the best possible in that framework. We also discuss consequences to the spectrum of Robin boundary value problems. Finally, we app...
