In addition, the numerical errors due to the transformation are investigated according as whether the diffusion term is fully derived or not. The numerical accuracy attributable to the full ...

In case the operators are infinite dimensional, the joint rank ∞-numerical range of the operators is a convex set closely related to the joint essential numerical ranges of the operators. The Journal ...

Parabolic partial differential equations (PDEs) are fundamental in modelling a wide range of diffusion processes in physics, finance and engineering. The numerical approximation of these equations ...
