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.
