The Functional Measure of Gauge Theories in the Presence of Gribov Horizons
C. Becchi, S. Giusto, C. Imbimbo
We discuss the formal structure of a functional measure for Gauge Theories preserving the Slavnov-Taylor identity in the presence of Gribov horizons. Our construction defines a gau…

A Lagrangian Formulation of 2-Dimensional Topological Gravity and Čech-De-Rham Cohomology
Carlo M. Becchi, Camillo Imbimbo
We present a very simplified analysis of how one can overcome the Gribov problem in a non-abelian gauge theory. Our formulae, albeit quite simplified, show that possible breakdowns…

A Functional and Lagrangian Formulation of Two-Dimensional Topological Gravity
C. M. Becchi, R. Collina, C. Imbimbo
We reconsider two-dimensional topological gravity in a functional and lagrangian framework. We derive its Slavnov-Taylor identities and discuss its (in)dependence on the background…
