Brs Cohomology of the Supertranslations in D=4

چکیده

Supersymmetry transformations are a kind of square root of spacetime translations. The corresponding Lie superalgebra always contains the supertranslation operator δ = c α σ µ α ˙ β c ˙ β (ǫ µ) †. We find that the cohomology of this operator depends on a spin-orbit coupling in an SU (2) group and has a quite complicated structure. This spin-orbit type coupling will turn out to be basic in the coho-mology of supersymmetric field theories in general.

On the Associated Primes of the generalized $d$-Local Cohomology Modules

The first part of the paper is concerned to relationship between the sets of associated primes of the generalized $d$-local cohomology modules and the ordinary  generalized local cohomology  modules.  Assume that $R$ is a commutative Noetherian local ring, $M$ and $N$  are  finitely generated  $R$-modules and $d, t$ are two integers. We prove that $Ass H^t_d(M,N)=bigcup_{Iin Phi} Ass H^t_I(M,N)...

Higher-Dimensional Supertranslations and Weinberg’s Soft Graviton Theorem

Asymptotic symmetries of theories with gravity in d = 2m+2 spacetime dimensions are reconsidered for m > 1 in light of recent results concerning d = 4 BMS symmetries. Weinberg’s soft graviton theorem in 2m + 2 dimensions is re-expressed as a Ward identity for the gravitational S-matrix. The corresponding asymptotic symmetries are identified with 2m + 2-dimensional supertranslations. An alternat...

Brs Cohomology in Topological String Theory and Integrable Systems

In cohomological field theory we can obtain topological invariants as correlation functions of BRS cohomology classes. A proper understanding of BRS cohomology which gives non-trivial results requires the equivariant cohomology theory. Both topological Yang-Mills theory and topological string theory are typical examples of this fact. After reviewing the role of the equivariant cohomology in top...
