We study the convergence to equilibrium of a class of nonlinear recombination models. In analogy with Boltzmann's H-theorem from kinetic theory, and in contrast with previous analysis of these models, ...
BUFFALO, N.Y. — In physics, the Fermi-Pasta-Ulam-Tsingou (FPUT) problem — which found that certain nonlinear systems do not disperse their energy, but rather return to their initial excited states — ...
