On a class of nonlinear variational inequalities:
High concentration of the graph of weak solution via its
fractional dimension and Minkowski content
Luka Korkut, Mervan Pasic
Abstract:
Weak continuous bounded solutions of a class of nonlinear
variational inequalities associated to onedimensional
pLaplacian are studied. It is shown that a kind of boundary
behaviour of nonlinearity in the main problem produces a kind of
high boundary concentration of the graph of solutions. It is
verified by calculating lower bounds for the upper
MinkowskiBouligand dimension and Minkowski content of the graph
of each solution and its derivative. Finally, the order of growth
for singular behaviour of the
norm of derivative of
solutions is given.
