Q-Exact Actions for BF Theories
نویسندگان
چکیده
The actions for all classical (and consequently quantum) BF theories on n-manifolds is proven to be given by anti-commutators of hermitian, nilpotent, scalar fermionic charges with Grassmann-odd functionals. In order to show this, the space of fields in the theory must be enlarged to include “mass terms” for new, non-dynamical, Grassmann-odd fields. The implications of this result on observables are examined. CTP # 2271 December 1993 hep-th/9401005 This work is supported in part by funds provided by the U. S.

Holomorphic Analogs of Topological Gauge Theories
We introduce a new class of gauge field theories in any complex dimension, based on algebra-valued (p, q)-forms on complex n-manifolds. These theories are holomorphic analogs of the well-known Chern-Simons and BF topological theories defined on real manifolds. We introduce actions for different special holomorphic BF theories on complex, Kähler and Calabi-Yau manifolds and describe a procedure ...
متن کاملEdge Dynamics for BF Theories and Gravity
We discuss BF theories defined on manifolds with spatial boundaries. Variational arguments show that one needs to augment the usual action with a boundary term for specific types of boundary conditions. We also show how to use this procedure to find the boundary actions for theories of gravity with first order formulations.
متن کامل1 BF Actions for the Husain - Kuchař Model
We show that the Husain-Kuchař model can be described in the framework of BF theories. This is a first step towards its quantization by standard perturbative QFT techniques or the spin-foam formalism introduced in the space-time description of General Relativity and other diff-invariant theories. The actions that we will consider are similar to the ones describing the BF-Yang-Mills model and so...

متن کاملLattice Actions for Yang-Mills Quantum Mechanics with Exact Supersymmetry
We derive lattice actions for Yang-Mills quantum mechanics for models with Q = 4, 8 and 16 supercharges which possess an exact supersymmetry at non-zero lattice spacing. These are obtained by dimensional reduction of twisted versions of the corresponding super Yang-Mills theories in D = 2, 3 and 4 dimensions. [email protected] [email protected]
