Cosmology and Geometry at the Boundary  Lecture II

13 Apr 2021  11:00
Cosmological observables, such as temperature fluctuations in the CMB and density fluctuations in the distribution of galaxies, can be traced back to the end of inflation where they are encoded in quantum correlations, and the wavefunction of the universe which generates them, at a spacelike boundary of a quasidS spacetime. These lectures will focus on a novel approach to construct the wavefunction of the universe from boundary data only and extract from them physical information. We will learn about its analytic structure, the interpretation of the singularity coefficients as physical processes, including scattering processes in flatspace, as well as a firstprinciple formulation in terms of combinatorialgeometrical objects which, together to provide new computational tools, provide a window on the basic rules behind cosmological processes.

Geometric Approach to Supergravity II

26 Mar 2021  11:00
Abstract
The construction of supergravity theories from the technical point of view is a nontrivial task. In particular, complications arise from the fact that fermionic representations are involved. It is therefore particularly useful to find an efficient method to deal with the technical labor in formulating supergravity theories. In these lectures we will explore the geometric (aka rheonomic) approach to supergravity theories in superspace, which allows a complete geometrical interpretation of supersymmetry.
