Brst Cohomology in Beltrami Parametrization
نویسنده
چکیده
We study the BRST cohomology within a local conformal Lagrangian eld theory model built on a two dimensional Riemann surface with no boundary. We deal with the case of the complex structure parametrized by Beltrami di erential and the scalar matter elds. The computation of all elements of the BRST cohomology is given.

BRST Cohomology and Its Application to QED
We construct the BRST cohomology under a positive-definite inner product and obtain the Hodge decomposition theorem at a non-degenerate state vector space V . The harmonic states isomorphic with a BRST cohomology class correspond to the physical Hilbert space with positive norm as long as the completeness of QBRST is satisfied. We explicitly define a “co-BRST” operator and analyze the quartet m...
متن کاملOn equivalence of Floer’s and quantum cohomology
We show that the Floer cohomology and quantum cohomology rings of the almost Kähler manifold M , both defined over the Novikov ring of the loop space LM , are isomorphic. We do it using a BRST trivial deformation of the topological A-model. The relevant aspect of noncompactness of the moduli of pseudoholomorphic instantons is discussed. It is shown nonperturbatively that any BRST trivial deform...
متن کاملConformal Structures of Surfaces ∗
This paper solves the problem of computing conformal structures of general 2manifolds represented as triangular meshes. We approximate the De Rham cohomology by simplicial cohomology and represent the Laplace-Beltrami operator, the Hodge star operator by linear systems. A basis of holomorphic one-forms is constructed explicitly. We then obtain a period matrix by integrating holomorphic differen...
متن کاملBRST cohomology of the critical W4 string
We study the cohomology of the critical W 4 string using the W 4 BRST charge in a special basis in which it contains three separately nilpotent BRST charges. This allows us to obtain the physical operators in three steps. In the first step we obtain the cohomology associated to a spin-four constraint only, and it contains operators of the c = 4 5 W 3 minimal model. In the next step, where the s...
متن کاملLorentz Invariance of the Pure Spinor BRST Cohomology for the Superstring
In a previous paper, the BRST cohomology in the pure spinor formalism of the su-perstring was shown to coincide with the light-cone Green-Schwarz spectrum by using an SO(8) parameterization of the pure spinor. In this paper, the SO(9, 1) Lorentz generators are explicitly constructed using this SO(8) parameterization, proving the Lorentz invariance of the pure spinor BRST cohomology.
