Resumen de Large-Time Behavior of the Solutions to Rosenau-Type Approximations to the Heat Equation
Thomas Rey, Giuseppe Toscani
In this article we study the large-time behavior of the solution to a general Rosenau type approximation to the heat equation [P. Rosenau, Phys. Rev. A (3), 46 (1992), pp. 12--15], by showing that the solution to this approximation approaches the fundamental solution of the heat equation (the heat kernel), but at a slower rate than the usual heat equation. This result is valid in particular for the central difference scheme approximation of the heat equation, a property which to our knowledge has never been observed before
