A11 (1996) 1183-1216 | Subject: | High Energy Physics - Theory; Exactly Solvable and Integrable Systems | hep-th nlin.SI solv-int | Affiliation: | Mathematics Dept., University of Illinois, Urbana, IL) and Boris Konopelchenko (Physics Dept., University of Lecce, Lecce, Italy and Budker Institute of Nuclear Physics, Novosibirsk, Russia | Abstract: | Basic quantities related to 2-D gravity, such as Polyakov extrinsic action, Nambu-Goto action, geometrical action, and Euler characteristic are studied using generalized Weierstrass-Enneper (GWE) inducing of surfaces. Connection of the GWE inducing with conformal immersion is made and varius aspects of the theory are shown to be invariant under the modified Veselov-Novikov hierarchy of flows. The geometry of certain surfaces is shown to be connected with the dynamics of infinite and finite dimensional integrable systems. Connections to Liouville-Beltrami gravity are indicated. | Source: | arXiv, hep-th/9506047 | Services: | Forum | Review | PDF | Favorites |
