摘要: In this paper, we compute the cohomology of the Heisenberg-Virasoro conformal algebra with coefficients in its modules, and in particular with trivial coefficients both for the basic and reduced complexes.关键词: Mathematics - Rings and Algebras ...
Cohomology of Conformal Algebras A class of infinite dimensional Lie algebras is discussed, which contains the centerless Virasoro subal-gebra. In this paper, the second cohomology group a... Bojko,Bakalov,Victor,... - 《Communications in Mathematical Physics》 被引量: 210发表: 1999年 ...
The purpose of this paper is to introduce the cohomology of various algebras over an operad of moduli spaces including the cohomology of conformal field theories (CFT's) and vertex operator algebras (VOA's). This cohomology theory produces a number of invariants of CFT's and VOA's, one of...
Modular invariance of trace functions in orbifold theory The goal of the present paper is to provide a mathematically rigorous foundation to certain aspects of rational orbifold conformal field theory, in other words the theory of rational vertex operator algebras and their automorphisms. Unde... C...

We describe the Virasoro analogues of the modified regular representations, which are vertex operator algebras with the total central charge equal to 26. The special values of the total central charges in the affine and Virasoro cases lead to the non-trivial semi-infinite cohomology with ...
