Chebyshev method for Helmholtz equation [PDF]

Archiv für Elektrotechnik, 1988
In the paper a generalization of the Global Element Method developed in [3] for elliptic boundary value problems to complex Helmholtz is regarded. The method in this case relies upon minimization of two functionals apart with respect to real and imaginary parts.

A fast Chebyshev’s method for quadratic equations

Applied Mathematics and Computation, 2004
In order to solve a quadratic equation \(F^{\prime \prime }(x)=B\), where \(B\) is a bilinear constant form, third-order methods are considered. To this end, the authors use multiresolution representation of data, standard forms of a matrix and of a bilinear operator and propose an adaptive Chebyshev method, whose convergence is proved (Theorem 1 ...

Analysis of Chebyshev Collocation Methods for Parabolic Equations

SIAM Journal on Numerical Analysis, 1986
Numerical approximations for the heat equation and the advection- diffusion equation in the cylinder are examined. The space discretization is based on the pseudospectral Chebyshev method, which is a collocation method at the Chebyshev Gaussian nodes. This method allows one to achieve high accuracy for smooth solutions.
