#### 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

#### 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
