Golden, Kenneth M. | Arbitrarily slow approach to limiting behavior | ABSTRACT. Let f(k, t): RN x [0, oo) -- R be jointly continuous in k and t, with lim(t)--(oo) f(k, t) = F(k) discontinuous for a dense set of k's. It is proven that there exists a dense set T of k's such that, for k e T , |f(k, t) - F(k)| approaches 0 arbitrarily slowly, i.e., roughly speaking, more ... | Random; Conductivity; Diffusion | 1991 |

Golden, Kenneth M. | Classical transport in quasiperiodic media | Abstract. Classical transport coefficients such as the effective conductivity or diffusivity of a quasiperiodic medium were observed [1] to depend discontinuously on the frequencies of the quasiperiodicity. For example, for a one-dimensional medium with a potential V(x) = cosx + coskx , the effecti... | Transport; Diffusion; Random | 1991 |
