I will describe elements of suitable morphism spaces in the category of bimodules over a factorizable ribbon Hopf algebra H that are invariant under a natural action of the mapping class group of m-punctured genus-g Riemann surfaces,for any m and g.These elements are candidates for the correlation functions in conformal field theories whose category of chiral sectors is equivalent to the category of H-modules.

The aim of this talk is to describe how Spin Foam Models can be used to construct normalized Borel measure spaces that carry the action of a group of diffeomorphisms of a manifold Diff(M).These measur
An introduction aimed at non-experts in loop quantum gravity will be given into the recently developed generalization of loop quantum gravity to higher dimensional supergravity.Possible applications w
A time-oriented semiclassical boundary state is introduced to calculate the correlation function in the Lorentzian Engle-Pereira-Rovelli-Livine spinfoam model.The resulting semiclassical correlation f
Spin foams are microscopic models for quantum gravity and space time.We discuss coarse graining methods to extract large scale physics from these model and derive consistency conditions that these mod
We introduce an action for three-dimensional gravity that mimics key features of the four-dimensional Holst-Plebanski theory.In particular,the action admits an extension with Barbero-Immirzi parameter
In this talk we will present a general method for finding all foams with given boundary and given number of internal vertices.We will apply the method to the Dipole Cosmology model and find all spin f
Coherent states proved to be useful both in defining spin foam models of Quantum Gravity as well as in deriving their asymptotic limits.The method of coherent states combined with stationary point ana
In recent times,there has been an explosion of interest in tensor models and their related field theories.Current research can be divided to a certain extent along two lines.The first regards the deve
A canonical formulation of the rank-three tensor model with a notion of local time is proposed.The consistency of the local time is guaranteed by a first-class constraint algebra.In a limit of localiz
The 2-dimensional Grosse-Wulkenhaar model is a super-renormalizable scalar field theory defined on the 2 dimensional noncommutative Moyal plane.I shall prove the Borel summability of the perturbation
