Discretization is a fundamental step in numerical analysis for the problemsdescribed by differential equations, and the difference between the continuousmodel and discrete model is one of the most important problems. In this paper,we consider the difference in the effect of the time-dependent propagationspeed on the energy estimate of the solutions for the wave equation and thesemi-discrete wave equation which is a discretization with respect to spacevariables.

On the energy estimates of semi-discrete wave equations with time dependent propagation speed
