We study properties of solitary wave solutions of three evolution equations arising in the modeling of internal waves Our experiments indicate that broad classes of initial data resolve into solitary waves but also suggest that solitary waves do not interact exactly thus suggesting two of these equa tions are not integrable In the course of our numerical simulations interesting meta stable quas...

Exotic stochastic processes are shown to emerge in the quantum evolution of complex systems Using in uence func tion techniques we consider the dynamics of a system coupled to a chaotic subsystem described through random matrix the ory We nd that the reduced density matrix can display dy namics given by L evy stable laws The classical limit of these dynamics can be related to fractional kinetic...

Despite their impor tance in assess ing the impact of pol i cies, out come eval u a tions—and in par tic u lar ran dom ized exper i ments—are rel a tively rare. The ratio nal iza tions used to jus tify the absence of out come eval u a tions include such asser tions as “we know our pro grams are work ing,” “they can’t pos si bly harm any one,” and “if they only help one kid they’re worth it.” Us...

Jonathan M. Borwein1, Xianfu Wang August 13, 1999 ABSTRACT. We prove a \typi al" subdi erentiability prin iple and apply it to a variety of omplete metri spa es of ontinuous fun tions on separable Bana h spa es; so as to obtain existen e of fun tions with maximal subdi erentials when ordered by in lusion. The relationship between ontinuous fun tions with maximal subdi erentials and nowhere mono...
