Research Interests

Main theme of research: nonlinear analysis and geometric function theory. This includes the topics listed below.

Linear and Nonlinear Elliptic PDEs:
  • Very weak solutions
  • Lp-regularity theory
  • Orlicz-Sobolev type estimates
  • Differential forms
The Calculus of Variations:
  • Weak convergence methods
  • Jacobian determinants and null Lagrangians
  • Polyconvex and quasiconvex functionals
  • Deformations of Finite Distortion:
  • Functions of one complex variable
  • Quasiregular mappings in Rn and the governing PDEs
  • Topological properties of weakly differentiable mappings between Riemannian manifolds
  • Harmonic Analysis Methods:
  • Singular integrals (sharp estimates)
  • Interpolation and nonlinear commutators
  • Hardy spaces
  • Such general topics intersect modern areas of applied mathematics; nonlinear elasticity, material science, microstructure of crystals and so forth.
