Stability and accuracy of difference schemes for hyperbolic problems [PDF]
, 1985 Bounds for the error order and error constant of full- and semidiscretizations of hyperbolic problems are given. In order to be able to compare fulldiscretizations a scaling is introduced.

Geometric Discretization of Lagrangian Mechanics and Field Theories [PDF]
, 2009 This thesis presents a unified framework for geometric discretization of highly oscillatory mechanics and classical field theories, based on Lagrangian variational principles and discrete differential forms. For highly oscillatory problems in mechanics,

On the continuum limit for a semidiscrete Hirota equation [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016 In this paper, we propose a new semidiscrete Hirota equation which yields the Hirota equation in the continuum limit. We focus on the topic of how the discrete space step δ affects the simulation for the soliton solution to the Hirota equation. The Darboux transformation and explicit solution

Convergence of a two-grid algorithm for the control of the wave equation [PDF]
, 2009 We analyze the problem of boundary observability of the finite-difference space semidiscretizations of the 2-d wave equation in the square.We prove the uniform (with respect to the meshsize) boundary observability for the solutions obtained by the two ...

Blow-up of continuous and semidiscrete solutions to elliptic equations with semilinear dynamical boundary conditions of parabolic type [PDF]
, 2007 In this paper we present existence of blow-up solutions for elliptic equations with semilinear boundary conditions that can be posed on all domain boundary as well as only on a part of the boundary. Systems of ordinary differential equations are obtained

On some boussinesq systems in two space dimensions: Theory and numerical analysis [PDF]
, 2007 A three-parameter family of Boussinesq type systems in two space dimensions is considered. These systems approximate the three-dimensional Euler equations, and consist of three nonlinear dispersive wave equations that describe two-way propagation of long

Semidiscretization for Time-Delayed Neural Balance Control [PDF]
SIAM Journal on Applied Dynamical Systems, 2015 Summary: The observation that time-delayed feedback can stabilize an inverted pendulum motivates the formulation of models of human balance control in terms of Delay Differential Equations (DDEs). Recently the intermittent, digital-like nature of the neural feedback control of balance has become evident.
