Asymptotic Analysis of Non-symmetric Linear Operators via Γ-convergence

چکیده

We study the asymptotic behavior of a sequence of Dirichlet problems for second order linear operators in divergence form { −div(σε∇u) = f in Ω, u ∈ H1 0 (Ω), where (σε) ⊂ L∞(Ω;Rn×n) is uniformly elliptic and possibly non-symmetric. On account of the variational principle of Cherkaev and Gibiansky [1], we are able to prove a variational characterization of the H-convergence of (σε) in terms of the Γ-convergence of suitably associated quadratic forms.

Asymptotic analysis for some linear eigenvalue problems via Gamma-Convergence

This paper is devoted to the analysis of the asymptotic behaviour when the parameter λ goes to +∞ for operators of the form −∆+λa or more generally, cooperative systems operators of the form (−∆+λa −b −c −∆+λd ) where the potentials a and d vanish in some subregions of the domain Ω. We use the theory of Γ-convergence, even for the non-variational cooperative system, to prove that for any reason...

The fast multipole method for the symmetric boundary integral formulation

A symmetric Galerkin boundary-element method is used for the solution of boundary-value problems with mixed boundary conditions of Dirichlet and Neumann type. As a model problem we consider the Laplace equation. When an iterative scheme is employed for solving the resulting linear system, the discrete boundary integral operators are realized by the fast multipole method. While the single-layer ...

On the approximation by Chlodowsky type generalization of (p,q)-Bernstein operators

In the present article, we introduce Chlodowsky variant of $(p,q)$-Bernstein operators and compute the moments for these operators which are used in proving our main results. Further, we study some approximation properties of these new operators, which include the rate of convergence using usual modulus of continuity and also the rate of convergence when the function $f$ belongs to the class Li...

Asymptotic analysis of periodically-perforated nonlinear media at and close to the critical exponent

We give a general Γ-convergence result for vector-valued non-linear energies defined on perforated domains for integrands with p-growth in the critical case p = n. We characterize the limit extra term by a formula of homogenization type. We also prove that for p close to n there are three regimes, two with a non trivial size of the perforation (exponential and mixed polynomial-exponential), and...

Adaptive FEM with Optimal Convergence Rates for a Certain Class of Nonsymmetric and Possibly Nonlinear Problems

We analyze adaptive mesh-refining algorithms for conforming finite element discretizations of certain non-linear second-order partial differential equations. We allow continuous polynomials of arbitrary, but fixed polynomial order. The adaptivity is driven by the residual error estimator. We prove convergence even with optimal algebraic convergence rates. In particular, our analysis covers gene...
