Nonlinear evolution problems with singular coefficients in the lower order terms

Fernando Farroni, Luigi Greco, Gioconda Moscariello +1

We consider a Cauchy Dirichlet problem for a quasilinear second order parabolic equation with lower order term driven by a singular coefficient. We establish an existence result to…

Noncoercive quasilinear elliptic operators with singular lower order terms

Fernando Farroni, Luigi Greco, Gioconda Moscariello +1

We consider a family of quasilinear second order elliptic differential operators which are not coercive and are defined by functions in Marcinkiewicz spaces. We prove the existence…

Diffeomorphic approximation of Planar Sobolev Homeomorphisms in rearrangement invariant spaces

Daniel Campbell, Luigi Greco, Roberta Schiattarella +1

Let $Ω \subseteq R^{2}$ be a domain, let $X$ be a rearrangement invariant space and let $f \in W^{1} X (Ω, R^{2})$ be a homeomorphism between $Ω$ and $f (Ω)$ . Then there e…

Atomic decompositions, two stars theorems, and distances for the Bourgain-Brezis-Mironescu space and other big spaces

Luigi D'Onofrio, Luigi Greco, Karl-Mikael Perfekt +2

Given a Banach space $E$ with a supremum-type norm induced by a collection of operators, we prove that $E$ is a dual space and provide an atomic decomposition of its predual. We ap…
