Postgraduate Seminars

Spring 2018

These seminars (unless otherwise stated) will take place on Thursdays at 1pm in Maths Room 706 (25 Gordon Street) on an (almost) weekly basis - see the map for further details. Talks are being given by 2nd and 3rd year Mathematics PhD students for PhD students.

11 January 2018

Speaker: Atheeta Ching

Supervisor(s): Dr Stephen Baigent

Title: Atheeta Vs. Predator

Abstract:
Competitive population systems are special in that there exists a unique, invariant manifold with some great properties! For example, all solution trajectories in the phase plane are actually asymptotic to one on this manifold meaning all non-trivial behaviours occur on this manifold. Our work explores if this still exists in systems where the species co-operate, or perhaps one becomes a predator/parasite...

25 January 2018

Speaker: Emily Maw

Supervisor(s): Dr Jonny Evans

Title: Vanishing cycles

Abstract:
I will talk about singularities, and how we can understand them via their so-called vanishing cycles. This topic beautifully illustrates how symplectic topology links algebraic geometry to low-dimensional topology. We will meet some basic examples, and hopefully get to "pinwheels", which are what I am studying! The talk will be highly nontechnical and mostly involve pictures, so should be accessible to all 😊

01 February 2018

Speaker: Yongjo Lee

Supervisor(s): Dr Christian Boehmer

Title: Soliton deformational wave solutions for nonlinear Cosserat micropolar elasticity

Abstract: After brief introduction of classical continuum and micro-continuum theory, I will show you how the equations of motion can be obtained from various energy functionals. In turn, these equations of motion lead to the soliton solutions via so-called double sine-Gordon equation. And I will show how the solutions can determine the overall deformational behaviour.

08 February 2018 in Room 500

Speaker: Sean Jamshidi

Supervisor(s): Prof Ted Johnson

Title: Coastal outflows into a buoyant layer

Abstract:
River water discharging into the ocean is a major source of sediments, nutrients and pollutants, and as such can both help and hinder the extraordinary variety of life that blooms in coastal regions. It is therefore important for conservationists and oceanographers to understand where river water goes, and the mechanisms by which it is transported. In this talk, I will provide an overview of these mechanisms, focussing particularly on the role played by potential vorticity. I will try to provide as much physical intuition as possible, while also giving a flavour of the mathematics that has been used to study this interesting and rich problem.
