The universal envelope of the topological closed string BRST - complex

چکیده
We construct a universal envelope for any Poissonand Gerstenhaber algebra. While the deformation theory of Poisson algebras seems to be partially trivial, results from string and M -theory suggest a rich deformation theory of Gerstenhaber algebras. We apply our construction in this case to well known questions on the topological closed string BRST-complex. Finally, we find a simliar algebraic structure, as for the universal envelope, in the SU (2)-WZW model.

Instanton amplitudes in open-closed topological string theory
I use the universal instanton formalism to discuss quantum effects in the openclosed topological string theory of a Calabi-Yau A-model, in the presence of a multiplywrapped ‘Floer’ D-brane. This gives a precise meaning (up to the issue of compactifying the relevant moduli spaces) to the instanton corrections which affect sigma model and topological string amplitudes. The cohomological formalism...
متن کاملThe Coupling of Chern-Simons Theory to Topological Gravity
We couple Chern-Simons gauge theory to 3-dimensional topological gravity with the aim of investigating its quantum topological invariance. We derive the relevant BRST rules and Batalin-Vilkovisky action. Standard BRST transformations of the gauge field are modified by terms involving both its anti-field and the super-ghost of topological gravity. Beyond the obvious couplings to the metric and t...

In general bosonic closed string backgrounds the ghost-dilaton is not the only state in the semi-relative BRST cohomology that can change the dimensionless string coupling. This fact is used to establish complete dilaton theorems in closed string field theory. The ghost-dilaton, however, is the crucial state: for backgrounds where it becomes BRST trivial we prove that the string coupling become...
متن کاملThe boundary state from open string fields
We construct a class of BRST-invariant closed string states for any classical solution of open string field theory. The closed string state is a nonlinear functional of the open string field and changes by a BRST-exact term under a gauge transformation of the solution. As a result, its contraction with an on-shell closed string state provides a gauge-invariant observable of open string field th...
متن کاملLie Superalgebra and Extended Topological Conformal Symmetry in Non - critical W 3 Strings
We obtain a new free field realization of N = 2 super W3 algebra using the technique of quantum hamiltonian reduction. The construction is based on a particular choice of the simple root system of the affine Lie superalgebra sl(3|2)(1) associated with a non-standard sl(2) embedding. After twisting and a similarity transformation, this W algebra can be identified as the extended topological conf...
