MULTISTRING SOLUTIONS IN INFLATIONARY SPACETIMES

Abstract

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