We present an a priori analysis of the hp-version of the finite element method for the primal formulation of frictional contact in linear elasticity. We introduce a new limiting case estimate for the interpolation error at Gauss and Gauss-Lobatto quadrature points. An hp-adaptive strategy is presented; numerical results shows that this strategy can lead to exponential convergence.
Abstract In their article “Coupling at a distance HDG and BEM” , Cockburn, Sayas Solano proposed an iterative coupling of the hybridizable discontinuous Galerkin method (HDG) boundary element (BEM) to solve exterior Dirichlet problem. The novelty numerical scheme consisted using computational domain for discretization whose did not coincide with interface. article, authors provided extensive ev...
We present a nonintrusive method for reliably estimating the noise level during quantum computation and quantum communication protected by quantum error-correcting codes. As preprocessing of quantum error correction, our scheme estimates the current noise level through a negligible amount of classical computation using error syndromes and updates the decoder’s knowledge on the spot before infer...

In this paper, numerical solution for the generalized Rosenau-Burgers equation is considered and Crank-Nicolson finite difference scheme is proposed. Existence of the solutions for the difference scheme has been shown. Stability, convergence and priori error estimate of the scheme are proved. Numerical results demonstrate that the scheme is efficient and reliable. Keywords—Generalized Rosenau-B...
We prove global well-posedness for the L-critical cubic defocusing nonlinear Schrödinger equation on R with data u0 ∈ H(R) for s > 1 3 . The proof combines a priori Morawetz estimates obtained in [4] and the improved almost conservation law obtained in [6]. There are two technical difficulties. The first one is to estimate the variation of the improved almost conservation law on intervals given...
A number of non-standard finite element methods have been proposed in recent years, each which derives from a specific class PDE-constrained norm minimization problems. The most notable examples are LL? methods. In this work, we argue that all high-order should be expected to deliver substandard uniform h-refinement convergence rates. fact, one may not even see rates proportional the polynomial...
