I study regularity properties of systems of partial differential equations.
I am most interested in systems where the equations are coupled. Such a couplings appear, e.g., if the systems has a nonlinearity like the p-Laplace system. An other way that systems are can be coupled is if only the symmetric part of the gradient appears instead of the full gradient. Such systems are studied in elasticity theory.
Recently, I also took interest in nonlocal nonlinear systems and their regularity properties.
