Morphisms of Cohomological Field Theories
We introduce a notion of morphism of CohFT’s, on the basis of the analogy with A∞ morphisms, and discuss the relationship with morphisms of F -manifolds introduced by Manin and Hertling [5]. The structure maps of a morphism of CohFT’s have as input a cohomology class on the moduli space of scaled affine lines (complexified multiplihedron) studied in Ma’u-Woodward [9]. The main result is a compu...
متن کاملCohomological aspects of gauge theories: superfield formalism
Some of the key cohomological features of the two (1+1)-dimensional (2D) free Abelianand self-interacting non-Abelian gauge theories (having no interaction with matter fields) are briefly discussed first in the language of symmetry properties of the Lagrangian densities and the same issues are subsequently addressed in the framework of superfield formulation on the four (2+ 2)-dimensional super...

متن کاملCohomological analysis of gauged-fixed gauge theories
The relation between the gauge-invariant local BRST cohomology involving the antifields and the gauge-fixed BRST cohomology is clarified. It is shown in particular that the cocycle conditions become equivalent once it is imposed, on the gauge-fixed side, that the BRST cocycles should yield deformations that preserve the nilpotency of the (gauge-fixed) BRST differential. This shows that the rest...
متن کاملCohomological Field Theories with Kähler Structure
Historically the cohomological field theory first has been introduced as a twisted version of global space-time supersymmetric quantum field theory, specifically the N = 2 supersymmetric Yang-Mills theory in four dimensional space-time [1]. The global space-time supersymmetry, by definition, requires the existence of a spinor which is constant everywhere on the space-time manifold M . A spinor ...
