Recently, physical fields with topological configurations are evoking increasing attention due to their fascinating structures both in fundamental researches an
This paper deals with Crouzeix-Raviart nonconforming finite element approximation of Navier-Stokes equation in a plane bounded domain, by using the so-called ve
The nickel-base alloy is one of the leading candidate materials for generation IV nuclear reactor pressure vessel. To evaluate its stability of helium damage an
There are two cases of the exterior problems of the Helmholtz equation. If λ > 0 the bilinear form is coercive, and if λ < 0 it is the scattering problem.We gi
We give definitions of real piecewise algebraic variety and its dimension. By using the techniques of real radical ideal, P-radical ideal, affine Hilbert polyno
