Approximations by orthonormal mapped Chebyshev functions for higher-dimensional problems in unbounded domains
This paper is concerned with approximation properties of orthonormal mapped Chebyshev functions (OMCFs) in unbounded domains. Unlike the usual mapped Chebyshev functions which are associated with weighted Sobolev spaces, the OMCFs are associated with the usual (non-weighted) Sobolev spaces. This leads to particularly simple stiffness and mass matrices for higher-dimensional problems. The approx...
متن کاملProblems in Unbounded Cylindrical Domains
We combine the classical point of view of special functions with functional calculus for sectorial operators to obtain semi-explicit representation formulæ for the solutions.The formulæ are well suited for the further study of their properties as well as for the precise characterization of asymptotic behaviour in the large or for vanishing parameters (such as in perturbation theory). The approa...
متن کاملSolving high-order partial differential equations in unbounded domains by means of double exponential second kind Chebyshev approximation
In this paper, a collocation method for solving high-order linear partial differential equations (PDEs) with variable coefficients under more general form of conditions is presented. This method is based on the approximation of the truncated double exponential second kind Chebyshev (ESC) series. The definition of the partial derivative is presented and derived as new operational matrices of der...
متن کاملElliptic and parabolic problems in unbounded domains
We consider elliptic and parabolic problems in unbounded domains. We give general existence and regularity results in Besov spaces and semi-explicit representation formulas via operatorvalued fundamental solutions which turn out to be a powerful tool to derive a series of qualitative results about the solutions. We give a sample of possible applications including asymptotic behavior in the larg...
متن کاملCritical Singular Problems on Unbounded Domains
with a continuous function a and a subcritical growth function g. This type of equation includes the Makutuma equation, when a(|x|) = 1/(1 + |x|2) and g(s) = |s|p−1s, with 1 < p < 2∗ − 1 = (N + 2)/(N − 2), which appears in astrophysics and scalar curvature equations on RN (see, e.g., [15, 17, 18]) In [16] Munyamarere and Willem obtained a result of multiplicity of nodal solutions for these equa...
