The extended finite element method (XFEM), also known as generalized finite
element method (GFEM) or partition of unity method (PUM) is a numerical technique that extends the
classical finite element method (FEM) approach by extending the solution space for solutions to differential
equations with d[r]

The notions of equivalence and strict equivalence for order one differential
equations of the form f(y

, y,z) = 0 are introduced. The more explicit
notion of strict equivalence is applied to examples and questions concerning
autonomous equations and equations having the Painleve property. The ´

This paper deals with the problem of global exponential stabilization for a
class of nonautonomous cellular neural networks with timevarying delays. The system
under consideration is subject to timevarying coefficients and timevaying delays. Two
cases of timevarying delays are considered: (i) the de[r]

We study the algebraic transfer constructed by Singer 26 using technique of the May spectral
sequence. We show that the two squaring operators, defined by Kameko 12 and Nakamura
21, on the domain and range respectively, of our E2 version of the algebraic transfer are
compatible. We also prove that t[r]

Algebraic combinatorics is an area of mathematics that employs methods of abstract algebra, notably group theory and representation theory, in various combinatorial contexts and, conversely, applies combinatorial techniques to problems in algebra.

The purpose of this paper is to study gradient estimate of Hamilton Souplet Zhang type

The eXtended Finite Element Method (XFEM) is implemented for modeling arbitrary discontinuities in
1D and 2D domains. XFEM is a partition of unity based method where the key idea is to paste together
special functions into the finite element approximation space to capture desired features in the sol[r]

Some properties of characteristic curves in connection with viscosity
solutions of HamiltonJacobi equations defined by Hopf formula are studied. We
are concerned with the points where the Hopf formula u(t, x) is differentiable, and

Abstract. This paper studies both nonautonomous stochastic differential
equations and stochastic differential delay equations with Markovian
switching. A new result on almost sure stability of stochastic
