Full Project Detail:

Quasilinear systems describe a class of nonlinear waves where dispersive effects can be neglected. Our team at Loughborough has proposed a novel approach to the study of such systems known as the method of hydrodynamic reductions [1]. In this project we will apply the method of hydrodynamic reductions to the investigation of first-order multi-component systems of hydrodynamic type in 2+1 dimensions. The ultimate goal is a complete description of integrable systems within this class. Quasilinear integrable systems are expected to have remarkable geometric/symmetry properties and are of prime importance for the classification of multidimensional dispersive integrable models.  We will apply the necessary differential-geometric condition for integrability coming from the theory of double waves [2].

Familiarity with differential equations, differential geometry and computer algebra (Mathematica, Maple) would be a valuable asset for this project.
