MULTISTRING SOLUTIONS IN INFLATIONARY SPACETIMES

High Energy Physics - Theory 2009-10-28 v1

Abstract

Multistring solutions of the string equations of motion are found for inflationary spacetimes with expansion factor R(η)ηkR(\eta)\propto \eta^k for any k<0k<0 and η\eta conformal time. If 0>k>10>k>-1 only two-string solutions can be found within our ansatz, whereas for k=11/nk=-1-1/n, with n=1,2,n=1,2,\ldots, multistring solutions exist with an infinite number of strings [In the special case k=2k=-2 we recover de Sitter spacetime where multistring solutions were first found].
