On 3+1 Dimensional Scalar Field Cosmologies
F. L. Williams, P. G. Kevrekidis, T. Christodoulakis +3
In this communication, we analyze the case of 3+1 dimensional scalar field cosmologies in the presence, as well as in the absence of spatial curvature, in isotropic, as well as in…

Remarks on harmonic maps, solitons, and dilaton gravity
Floyd L. Williams
Another connection of harmonic maps to gravity is presented. Using 1-soliton and anti-soliton solutions of the sine-Gordon equation, we construct a pair of harmonic maps that we ex…
