Nonlinear elliptic systems with quadratic growth
No full textWe consider nonlinear elliptic systems
div (A(x,u)\cdot Du) = f(x,u,Du)
with a right-hand side of quadratic growth
|f(x,u,p)|<= a|p|^2 + b
Under suitable assumptions we show that every solution
of such system is regular, except possibly on a closed set, whose codimension is greater that two
Researches on the equilibrium of masonry structures
No full textIn this paper we introduce some new classes of functions, among these a class of weak diffeomorphisms. In these classes we prove by direct methods the existence of minimizers for several kinds of variational integrals. In particular, we prove the existence of one-to-one orientation-preserving maps that minimize suitable energies associated with hyperelastic materials. The minimizers are also proved to satisfy equilibrium equations. Finally radial deformations are discussed in connection with cavitation
