Yulia Timofeeva: Computational modelling of neurotransmitter release

11:00am, Zoom

Increases in concentration of free calcium ions (Ca2+) in presynaptic terminals of neuronal cells trigger vesicular release of neurotransmitters. Changes in Ca2+ concentration are primarily due to Ca2+ influx through voltage-gated calcium channels located at the plasma membrane and activated during an action potential or spontaneously. In this talk I will demonstrate how experimentally constrained computational modelling of underlying biological processes can complement laboratory studies (using electrophysiology and imaging techniques) and provide insights into the mechanisms of synaptic transmission.

Lucy Moser-Jauslin: Smooth rational affine varieties with infinitely many real forms

1:00pm, Zoom.

In this talk, I will discuss a recent result concerning real forms of affine varieties. Given a real variety X, a real form of X is a real variety Y such that the complexifications of X and Y are isomorphic as complex varieties. I will show how to construct smooth rational affine algebraic varieties of dimension 4 or higher which admit infinitely many non-isomorphic real forms. This is joint work with A. Dubouloz and G. Freudenburg.

Mathew Bullimore: New algebraic structures in quantum field theory

2:00pm, https://durhamuniversity.zoom.us/j/97251974399?pwd=Tmw4WGVnVkRUWGlNbUJzU3FpS0FBdz09

In recent years, remarkable algebraic structures have been discovered in the quest to perform exact non-perturbative computations in supersymmetric quantum field theory, with deep connections to geometry and representation theory. I will try to explain how some these algebraic structures arise in simple examples, including Landau levels on a sphere, monopoles creating and destroying vortices, and interfaces colliding with boundaries.
