Applications are invited for a self-funded, 3 year full-time or 6 year part-time PhD project.

The PhD will be based in the School of Mathematics and Physics and will be supervised by Dr Thomas Kecker.

This PhD project will offer a unique opportunity to apply cutting-edge techniques originating in algebraic geometry to the study of certain classes of complex differential equations. The PhD project will build on recent work by Dr Thomas Kecker (supervisor) on the singularity structure of solutions of complex differential equations. This work has successfully applied the method of computing the spaces of initial values under continued ‘blowing up’ of ‘base points’ for certain classes of non-linear differential equations, for which one can essentially obtain a complete list of the different types of (movable) singularities that the solutions of the equations can exhibit in the complex plane. It has thus been demonstrated that the space of initial values, originally constructed for the (integrable) Painlevé equations, is a useful concept also for much more general classes of (non-integrable) equations. Building on this work, the PhD project aims at applying and extending this methodology to wider classes of equations and to automate the procedure of computing the space of initial values using computer algebra software, thus providing a useful tool for other researchers to determine the nature of the singularities of solutions of differential equations. It is also known that the geometric properties of the space of initial values, in the case of the Painlevé equations, is reflected in the symmetries of these equation as so-called Bäcklund transformations, a non-linear analogue of raising and lowering operators in linear differential equations. The project will investigate to what extent this also applied to more general classes of equations, connecting the geometric and algebraic properties of an equation. The project will thus involve a unique combination of complex analysis, algebra and geometry to answer fundamental questions in the field of complex differential equations.
