The ‘BRST-invariant ’ Condensate of Dimension Two in QCD
, 2003
"... The status of the ‘BRST-invariant ’ condensate of mass dimension two in QCD is explained. The condensate is only invariant under an ‘on-shell ’ BRST symmetry which includes a partial gauge fixing. The on-shell BRST symmetry represents the residual gauge symmetry under gauge transformations which pre ..."

preserve the partial gauge fixing. The gauge-invariant operators which correspond to the BRST-invariant condensate are identified in the Lorentz and maximal Abelian gauges and are shown to be invariant under the residual gauge transformations.
UCSBTH-91-47 Correlators of Special States in c=1 Liouville Theory
, 1991
"... We genaralize the ground ring struture to all other special BRST invariant operators in the right branch in the c = 1 Liouville theory. we also discuss correlation functions of special states on the sphere. 10/91 ..."

UT-HEP-696-94 hepth/9412226 Calculation of Gromov-Witten invariants
, 1994
"... Using the associativity relations of the topological Sigma Models with target spaces, CP 3,CP 4 and Gr(2,4) , we derive recursion relations of their correlation and evaluate them up to certain order in the expansion over the instantons. The expansion coeffieients are regarded as the number of ration ..."

A PROOF OF BRST INVARIANCE
"... Abstract Introducing a geometric normal ordering, we give a proof of BRST invariance of the states associated to an arbitrary genus Riemann surface with a puncture, in the operator formalism. FTUAM/88-35 * Work supported in part by the program 'Ayudas para estancias breves en centros de invest ..."

(Non)triviality of Pure Spinors and Exact Pure Spinor- RNS Map
, 2008
"... All the BRST-invariant operators in pure spinor formalism in d = 10 can be represented as BRST commutators, such as V = {Qbrst, θ+ λ+ V} where λ+ is the U(5) component of the pure spinor transforming as 1 5. Therefore, in order to secure non-triviality of BRST 2 cohomology in pure spinor string theo ..."

BV-STRUCTURE OF THE COHOMOLOGY OF NILPOTENT SUBALGEBRAS AND THE GEOMETRY OF (W-) STRINGS
, 1995
"... Given a simple, simply laced, complex Lie algebra g corresponding to the Lie group G, let n+ be the subalgebra generated by the positive roots. In this paper we construct a BV-algebra BV[g] whose underlying graded commutative algebra is given by the cohomology, with respect to n+, of the algebra of ..."

of regular functions on G with values in ∧ (n+\g). We conjecture that BV[g] describes the algebra of all physical (i.e., BRST invariant) operators of the noncritical W[g] string. The conjecture is verified in the two explicitly known cases, g = sl2 (the Virasoro string) and g = sl3 (the W3 string). USC-95
Comments on the Equivalence between Chern-Simons Theory and Topological Massive Yang-Mills Theory in 3D
, 2002
"... The classical formal equivalence upon a redefinition of the gauge connection between Chern-Simons theory and topological massive Yang-Mills theory in three-dimensional Euclidean spacetime is analyzed at the quantum level within the BRST formulation of the Equivalence Theorem. The parameter controlli ..."

expansion by a recursive choice of non-invariant counterterms. The Green functions of local operators constructed only from the (λ-dependent) transformed gauge connection, as well as those of BRST invariant operators, are shown to be independent of the parameter λ, as a consequence of the validity of the ST
Quantum BRST properties of reparametrization invariant theories
"... Any regular quantum mechanical system may be cast into an abelian gauge theory by simply reformulating it as a reparametrization invariant theory. We present a detailed study of the BRST quantization of such reparametrization invariant theories within a precise operator version of BRST. The treatmen ..."
