چکیده
Exterior Dirichlet problems for two-dimensional (2D) lattice waves on the infinite triangular are considered. Namely, we study 2D discrete Helmholtz equation in a plane with hole. New results obtained existence and uniqueness of solution case real wave number [Formula: see text] without passing to complex number. Besides, Green’s representation formula is derived help difference potentials. To demonstrate results, propose method numerical calculation.

Triangular Lattice Potts Models
In this paper we study the 3-state Potts model on the triangular lattice which has twoand three-site interactions. Using a Peierls argument we obtain a rigorous bound on the transition temperature, thereby disproving a conjecture on the location of its critical point. Low-temperature series are generated and analyzed for three particular choices of the coupling constants; a phase diagram is the...
متن کاملHardy space method for exterior Maxwell problems
A relevant difference between (9) and least squares formulations is that the former can be used to prove k-explicit stability bounds on u, while the seconds requires these bounds to be well-posed. We note that, using an appropriate operator T : V → V , any well-posed formulation in the form (2) can be translated in a sign-definite one: aT (u, v) := a(u, T v) = F (Tv) =: FT (v). However, the ope...
متن کاملFinite Element Exterior Calculus for Parabolic Problems
In this paper, we consider the extension of the finite element exterior calculus from elliptic problems, in which the Hodge Laplacian is an appropriate model problem, to parabolic problems, for which we take the Hodge heat equation as our model problem. The numerical method we study is a Galerkin method based on a mixed variational formulation and using as subspaces the same spaces of finite el...
متن کاملFinite Element Exterior Calculus for Evolution Problems
ABSTRACT. Arnold, Falk, and Winther [Bull. Amer. Math. Soc. 47 (2010), 281–354] showed that mixed variational problems, and their numerical approximation by mixed methods, could be most completely understood using the ideas and tools of Hilbert complexes. This led to the development of the Finite Element Exterior Calculus (FEEC) for a large class of linear elliptic problems. More recently, Hols...
متن کاملComposite Laguerre-Legendre PseudospectralMethod for Exterior Problems
In this paper, we propose a composite Laguerre-Legendre pseudospectral method for exterior problems with a square obstacle. Some results on the composite Laguerre-Legendre interpolation, which is a set of piecewise mixed interpolations coupled with domain decomposition, are established. As examples of applications, the composite pseudospectral schemes are provided for two model problems. The co...
