Thesis title: Regularity of solutions to nonlinear thin and boundary obstacle problems
Variational inequalities with thin obstacles and Signorini-type boundary conditions are classical problems in the calculus of variations, arising in numerous applications.
In the linear case many refined results are known, while in the nonlinear setting our understanding is still at a preliminary stage.
The thesis is about C^1 regularity for the solutions to a general class of quasi-linear variational inequalities with thin obstacles and C^{1,α} regularity for variational inequalities under Signorini-type conditions on the boundary of a domain.
