Topological gravity with exchange algebra
S. Aoyama
A topological gravity is obtained by twisting the effective super\-gravity. We show that this topological gravity has an infinite number of BRST invariant quantities with c…
Construction of topological field theories using BV
F. De Jonghe, S. Vandoren
We discuss in detail the construction of topological field theories using the Batalin--Vilkovisky (BV) quantisation scheme. By carefully examining the dependence of the antibracket…
Hidden symmetries, special geometry and quaternionic manifolds
B. de Wit, A. Van Proeyen
The moduli space of the Calabi-Yau three-folds, which play a role as superstring ground states, exhibits the same {\em special geometry} that is known from nonlinear sigma models i…
Orthogonal matrix polynomials and higher order recurrence relations
Antonio J. Durán, Walter Van Assche
It is well-known that orthogonal polynomials on the real line satisfy a three-term recurrence relation and conversely every system of polynomials satisfying a three-term recurrence…
Quantization of the topological -model and the master equation of the BF formalism
S. Aoyama
We quantize the topological -model. The quantum master equation of the Batalin-Vilkovisky formalism appears as a condition which eliminates the exact states from the B…
Chiral Quantization on a Group Manifold
Zbigniew Hasiewicz, Przemysł{aw} Siemion, Walter Troost
The phase space of a particle on a group manifold can be split in left and right sectors, in close analogy with the chiral sectors in Wess Zumino Witten models. We perform a classi…
Higher-spin strings and W minimal models
H. Lu, C. N. Pope, K. Thielemans +1
We study the spectrum of physical states for higher-spin generalisations of string theory, based on two-dimensional theories with local spin-2 and spin- symmetries. We explore t…
Simplifications in Lagrangian BV quantization exemplified by the anomalies of chiral gravity
S. Vandoren, A. Van Proeyen
The Batalin--Vilkovisky (BV) formalism is a useful framework to study gauge theories. We summarize a simple procedure to find a a gauge--fixed action in this language and a way to…
Regularisation of non-local actions in two-dimensional field theories
A. Sevrin, R. Siebelink, W. Troost
Taking the induced action for gauge fields coupled to affine currents as an example, we show how loop calculations in non-local two-dimensional field theories can be regulated. Our…
Non-abelian Harmonic Oscillators and Chiral Theories
Z. Hasiewicz, P. Siemion
We show that a large class of physical theories which has been under intensive investigation recently, share the same geometric features in their Hamiltonian formulation. These dyn…
Extensions of the Virasoro Algebra and Gauged WZW Models
A. Sevrin, W. Troost
To any non-trivial embedding of sl(2) in a (super) Lie algebra, one can associate an extension of the Virasoro algebra. We realize the extended Virasoro algebra in terms of a WZW m…
The Batalin-Vilkovisky Formalism on Fermionic Kaehler Manifolds
S. Aoyama, S. Vandoren
We show that the Kaehler structure can be naturally incorporated in the Batalin-Vilkovisky formalism. The phase space of the BV formalism becomes a fermionic Kaehler manifold. By i…
Schwinger--Dyson BRST symmetry and the Batalin--Vilkovisky Lagrangian Quantisation of Gauge Theories with Open or Reducible Gauge Algebras
Frank De Jonghe
In this short note we extend the results of Alfaro and Damgaard on the origin of antifields to theories with a gauge algebra that is open or reducible.
The Relation between Linear and Non-Linear Supergravity Theories
Alexander Sevrin, Kris Thielemans, Walter Troost
The effective actions for , chiral supergravities with a linear and a non-linear gauge algebra are related to each other by a quantum reduction, the latter is obtained…
Induced and Effective Gravity Theories in D=2
Alexander Sevrin, Kris Thielemans, Walter Troost
As a preparation for the study of {\it arbitrary} extensions of gravity we present a detailed investigation of supergravity. By gauging a chiral, nilpotent subgroup o…
Schwinger-Dyson BRST-Symmetry and the Equivalence of Hamiltonian and Lagrangian Quantistion
Frank De Jonghe
Implementing the requirement that a field theory be invariant under Schwinger-Dyson BRST symmetry in the Hamiltonian formalism, we show the equivalence between Hamiltonian and Lagr…
Master Equations for Extended Lagrangian BRST Symmetries
P. H. Damgaard, F. De Jonghe
Starting from the requirement that a Lagrangian field theory be invariant under both Schwinger-Dyson BRST and Schwinger-Dyson anti-BRST symmetry, we derive the BRST--anti-BRST anal…
Klein-Gordon-Langevin Quantum Geometry
F. Vanderseypen
We present a quantum geometric framework for stochastic quantisation in the case of a free Klein-Gordon field on Euclidean space. In this approach the noise is part of the backgrou…
Hiding Anomalies
F. De Jonghe, R. Siebelink, W. Troost
Anomalies can be anticipated at the classical level without changing the classical cohomology, by introducing extra degrees of freedom. In the process, the anomaly does not quite d…
The Global Minimum of Energy Is Not Always a Sum of Local Minima - a Note on Frustration
Jacek Miekisz
A classical lattice gas model with translation-invariant finite range competing interactions, for which there does not exist an equivalent translation-invariant finite range nonfru…
