摘要: In questo lavoro viene applicata all’elasticita non lineare un’idea che Ennio De Giorgi ha dimostrato essere feconda in contesti diversi, ad esempio nello studio delle superfici minime o della Γ-convergenza. Si tratta cosiddetta “estensione dello spazio ambiente”: e opportuno ricercare a priori cartesiane di area minima nella classe BV funzioni variazione limitata, piuttosto tra le C 1, come pure problemi Γ-convergenza esistenza del minimo integrali calcolo variazioni estendere lo ambiente 1 fino uno Sobolev H 1,p , od anche perfino L p .
