CONVERGENCE OF A SEMI-DISCRETE SCHEME FOR THE CURVE SHORTENING FLOW
Mathematical Models and Methods in Applied Sciences, 1994Convergence for a spatial discretization of the curvature flow for curves in possibly higher codimension is proved in L∞((0, T), L2(ℝ/2π)) ∩ L2((0, T) H1(ℝ/2π)). Asymptotic convergence in these norms is achieved for the position vector and its time derivative which is proportional to curvature.

Mathematics of Computation, 2023
We consider a fully discrete scheme for stochastic Allen-Cahn equation in a multi-dimensional setting. Our method uses a polynomial based spectral method in space, so it does not require the elliptic operator A A and the covariance operator

FLUID SIMULATION USING AN ADAPTIVE SEMI-DISCRETE CENTRAL-UPWIND SCHEME
International Journal of Computational Methods, 2007In this paper, we propose an adaptive semi-discrete central-upwind scheme on triangular meshes to approximate the solutions of hyperbolic conservation laws in gas dynamics: a local smoothness indicator is implemented to identify discontinuous solution regions; away from the discontinuities, a simple and computationally economical flux is used; near ...

Security Control for Networked Discrete-Time Semi-Markov Jump Systems With Round-Robin Protocol
IEEE Transactions on Circuits and Systems - II - Express Briefs, 2022This brief investigates the security control for a class of networked discrete-time semi-Markov jump systems subject to round-robin protocol. Considering the deception attack and round-robin protocol, observer-based security control scheme is first ...

A semi‐discrete convergent scheme for a quasilinear hyperbolic equation
Numerical Methods for Partial Differential Equations, 1987AbstractWe establish here the convergence (thereby proving the existence) of a semi‐discrete scheme for the quasilinear hyperbolic equation magnified image where x ∈ Rn, t ∈ [0,T], and ϕ ∈ L∞ (Rn). It is well known that the above problem does not necessarily have global classical solutions and the usual concepts of weak solution.

New High-Resolution Semi-discrete Central Schemes for Hamilton–Jacobi Equations
Journal of Computational Physics, 2000The subject of this paper is a finite difference scheme for the Hamilton - Jacobi equation \[ \phi_t+H(\nabla_x\phi)=0, \] where \(H\) is the Hamiltonian and \(x=(x_1,x_2,\cdots,x_d)\). The proposed scheme is of central type i.e. values of the function \(\phi\) and its space derivatives are computed (in the case of one space dimension), in the point ...

Semi-discrete finite-element approximation of nonlocal hyperbolic problem
Applicable Analysis, 2020In this paper, we investigate a semi-discrete finite-element approximation of nonlocal hyperbolic problem. A priori error estimate for the semi-discrete scheme is derived. A fully discrete scheme based on backward difference method is constructed.
