Partial differential equations, their numerical analysis and mathematical modelling
Partial differential equations with special attention to mathematical models in science and engineering. The research covers: Function spaces (distributions, Sobolev spaces, etc); existence, uniqueness, regularity and singularity properties of solutions, singularly perturbed problems; numerical treatment by finite element, finite difference and boundary element methods; dynamical systems; interval methods; modification of mathematical models.
The study of dense singularities of solutions of nonlinear partial differential equations with emphasis on Lie semigroups of noninvertible transformations of solutions; abstract differential geometry of algebras of generalised functions and de Rham cohomology; space-time foam structures with dense singularities.
