Research interests
Continuous and Discrete Integrable Systems
I am interested in connections between continuous (ODEs, PDEs) and discrete (recurrence relations, lattice equations) integrable systems. These connections can be realised in one direction using Darboux transformations, or on the opposite direction using appropriate continuum limits. To this end, recently, I have been working on birational solutions of Yang-Baxter type equations and on their integrable dynamics.
Mathematical Physics
I am interested in Partial Differential Equations of mathematical physics that can be considered, in one way or another, as integrable. In particular, I am interested in their symmetry structure, conservation laws and in properties and structure of their solution space; in particular their soliton type solutions.
Algebraic methods in the study of Differential Equations
Using the theory of Lie groups and Lie algebras one can study symmetry properties of differential equations (both ordinary and partial). These properties are key ingredient for a deeper understanding of a given differential equation and can be used to simplify, find exact solutions, or even construct conservation laws associated with the differential equation at hand. These methods are algorithmic and even apply to nonlinear differential equations. At the moment I am interested in Lie symmetries of certain elliptic partial differential equations that appear in the calculus of variations and in the classification of their solutions.
