The problem of integration in finite terms
WebbThis paper presents an algorithm based on the spectral Laguerre method for approximation of time derivatives as applied to a problem of seismic wave propagation in porous media with energy dissipation. The initial system of equations is written as a first-order hyperbolic system in terms of velocities, stresses, and pore pressure.

WebbIn this article, the direct and inverse problems for the one-dimensional time-dependent Volterra integro-differential equation involving two integration terms of the unknown function (i.e., with respect to time and space) are considered. In order to acquire accurate numerical results, we apply the finite integration method based on shifted Chebyshev …
