In this paper we extend the standard Ultra Weak Variational Formulation (UWVF) of Maxwell’s equations in an isotropic medium to the case of an anisotropic medi
This paper investigates various Weber problems including unconstrained Weber problems and constrained Weber problems under l1,l2 and l∞-norms. First with a tra
A T-mesh is basically a rectangular grid that allows T-junctions. Recently, Deng etal introduced splines over T-meshes, which are generalizations of T-splines i
The well known Wilson’s brick is only convergent for regular cuboid meshes. In this paper a quasi-Wilson element of three dimension is presented which is conve
We estimate error bounds between teary subdivision curves/surfaces and their control polygons after k-fold subdivision in terms of the maximal differences of th
