Description
Instanton-like solutions characterizing the geometric structure of the manifold are found to be in a two-dimensional theory of gravity with dynamical metric and torsion in the context of string theory. The eigenmodes for fluctuations of the solutions of the equations are also investigated and it has been shown that these solutions are stable. (orig.)
