Research Fellow in Mathematical Physics @ University of Melbourne

You will undertake high level research addressing representation-theoretic aspects of affine vertex algebras and superalgebras at non-integral levels, the corresponding conformal field theories, and related fields including the theory of modular forms, tensor categories and symmetric functions. 92 more words

Jacobi stability analysis of scalar field models with minimal coupling to gravity in a cosmological background [CL]

http://arxiv.org/abs/1609.05636

We perform the study of the stability of the cosmological scalar field models, by using the Jacobi stability analysis, or the Kosambi-Cartan-Chern (KCC) theory. In the KCC approach we describe the time evolution of the scalar field cosmologies in geometric terms, by performing a “second geometrization”, by considering them as paths of a semispray. 211 more words

Is there a way to give a meaning to these sums?  That is, to sum them?

Integrable Cosmological Potentials [CL]

http://arxiv.org/abs/1608.08511

The problem of classification of the Einstein–Friedman cosmological Hamiltonians $H$ with a single scalar inflaton field $\varphi$ that possess an additional integral of motion polynomial in momenta on the shell of the Friedman constraint $H=0$ is considered. 109 more words
