[.]). In most of cases namely such conforming triangulations are used in the finite element modelling and analysis

Resonators with Curved Mirrors, the mathematical formulation of a particular physical problem. We take advantage of maximum and comparison principles in these situations. Maximum and comparison principles are fundamental properties of partial differential equations of second order. There are different formulations of these princi

Turing Patterns in Nonlinear Optics,itten in the form . where . is the electric field strength, . is the magnetic field strength, ε is the electric permittivity and μ, is the magnetic permeability (see [.] and [.] for more details). The two material parameters can depend on the spatial coordinates. It is well-known that the divergence
