Topological charges for branes in M-theory
We propose a simple form for the superalgebra of M2 and M5-brane probes in arbitrary supersymmetric backgrounds of 11d supergravity, extending previous results in the literature. In particular, we identify the topological charges in the algebras and find BPS bounds for the energies. The charges are given by the integral over a brane’s spatial worldvolume of a certain closed form built out of th...
متن کاملA quantization of topological M theory
A conjecture is made as to how to quantize topological M theory. We study a Hamiltonian decomposition of Hitchin’s 7-dimensional action and propose a formulation for it in terms of 13 first class constraints. The theory has 2 degrees of freedom per point, and hence is diffeomorphism invariant, but not strictly speaking topological. The result is argued to be equivalent to Hitchin’s formulation....
متن کاملProposal of a Topological M(atrix) Theory
Keeping in mind the several models of M(atrix) theory we attempt to understand the possible structure of the topological M(atrix) theory “underlying” these approaches. In particular we are motivated by the issue about the nature of the structure of the vacuum of the topological M(atrix) theory and how this could be related to the vacuum of the electroweak theory. In doing so we are led to a sim...
متن کاملM-theory and a Topological String Duality
We show how the topological string partition function, which is known to capture the degeneracies of a gas of BPS spinning M2-branes in M-theory compactified to 5 dimensions, is related to a 4-dimensional D-brane system that consists of single D6-brane bound to lower-dimensional branes. This system is described by a topologically twisted U(1) gauge theory, that has been conjecturally identified...
متن کاملM-Theory and Topological Strings–I
The RF 2g−2 terms of Type IIA strings on Calabi-Yau 3-folds, which are given by the corresponding topological string amplitudes (a worldsheet instanton sum for all genera), are shown to have a simple M-theory interpretation. In particular, a Schwinger one-loop computation in M-theory with wrapped M2 branes and Kaluza-Klein modes going around the loop reproduces the all genus string contribution...
