# Matthew Egginton

I am a final year PhD student under the supervision of Florian Theil and Ian Melbourne, interested in kinetic theory and the justification of the Boltzmann equation.

### Masters Dissertation (2014)

I worked with Florian Theil for my masters dissertation. It is based on an idea by Richard D James called objective molecular dynamics. He suggests the use of this structure as a generalisation of spatial homogeneity for the Boltzmann equation. Explicitly, one assumes an ansatz of the form $f(t,y,v)= g(t, y-Cv)$ which corresponds to assuming there is some spatial periodicity of the solution.

Within this type of solution, the particular form of $g(t,w)= \eta(t)^dG(\eta w)$ gives the explicit evolution of energy and entropy in terms of the initial distribution and $\eta$.

The project culminates in showing that there shouldn't be a solution of this form when one takes $C=a\otimes n$ for two perpendicular vectors $a,n$.

### RSG (2013-14)

I worked on an industrial based project with Jack Skipper and Jamie Lukins. The project initially involved understanding the details of problem the industrial links were having.

Following on from this, we then transformed the problem into a mathematically tractable problem, that of approximation of a function. We then applied least squares approximation to this, with reasonable results.

The report of the project can be found here, which explains in details the methods

We also gave a presentation on the project, and the slides used in this can be found here. We also presented a poster as well. We also have a webpage with some other information on it, whose link can be found here.

### MMath Dissertation (2012-13)

In my final year at Warwick I wrote a dissertation on the Interacting Bose Gas on the Lattice with Daniel Ueltschi.

### Second Year Essay

In my second year at Warwick I wrote an essay on Hilbert's Third Problem. This is the problem pertaining to scissors congruence of polyhedra.

## Lecture Notes

I have latexed various different lecture courses I went to. They are in various states of repair, and any comments, or corrections, would be most gratefully received.
