 | SO(7,7) structure of the SM fermions Speaker(s): Kirill Krasnov
Abstract: I will describe the relevant representation theory that allows to think of all components of fermions of a single generation of the Standard Model as components of a single Weyl spinor of an orthogonal group whose complexification is SO(14,C). There are then only two real forms tha... read more

 | Formulations of General Relativity (Part 4 of 4) Speaker(s): Kirill Krasnov
Abstract: The goal of this series is to collect various different formulations of General Relativity, with emphasis on four spacetime dimensions and formulations that use differential forms. The (non-exhaustive) list of formulations to be covered is per this plan:
Lecture 1): Motivations, fol... read more

 | Diffeomorphism Invariant Gauge Theories Speaker(s): Kirill Krasnov
Abstract: I will describe a very large class of gauge theories that do not use any external structure such as e.g. a spacetime metric in their construction. When the gauge group is taken to be SL(2) these theories describe interacting gravitons, with GR being just a particular member of a whole family of grav... read more

 | Deformations of General Relativity Speaker(s): Kirill Krasnov
Abstract: I will describe a very special (infinite-parameter) family of gravity theories that all describe, exactly like General Relativity, just two propagating degrees of freedom. The theories are obtained by generalizing Plebanski's self-dual (chiral) formulation of GR. I will argue that this class of grav... read more

 | Renormalizable Non-Metric Quantum Gravity? Speaker(s): Kirill Krasnov
Abstract: We argue that four-dimensional quantum gravity may be essentially renormalizable provided one relaxes the assumption of metricity of the
theory. We work with Plebanski formulation of general relativity in which the metric (tetrad), the connection as well as the curvature are all independent variab... read more
