Simplectic geometry and the canonical variables for Dirac-Nambu-Goto and Gauss-Bonnet system in string theory
نویسنده
چکیده
Using a strongly covariant formalism given by Carter for the deformations dynamics of p-branes in a curved background and a covariant and gauge invariant geometric structure constructed on the corresponding Witten’s phase space, we identify the canonical variables for Dirac-Nambu-Goto [DNG] and Gauss-Bonnet [GB] system in string theory. Future extensions of the present results are outlined.

متن کاملDeformation dynamics and the Gauss-Bonnet topological term in string theory
We show that there exist a nontrivial contribution on the Witten covariant phase space when the GaussBonnet topological term is added to the Dirac-Nambu Goto action describing strings, because of the geometry of deformations is modified, and on such space we construct a symplectic structure. Future extensions of the present results are outlined.

We examine the relativistic Nambu–Goto model with Gauss–Bonnet boundary term added to the action integral. The dynamical system is analysed using an invariant representation of string degrees of freedom by complex Liouville fields. The solutions of classical equations of motion for open strings are described.
