1. Second order elliptic operators with diffusion coefficients growingas |x|α at infinity.

Author

Sobajima, Motohiro and Spina, Chiara

Subjects
*ELLIPTIC operators, *DIFFUSION coefficients, *MATHEMATICAL proofs, *INFINITY (Mathematics), *SEMIGROUPS (Algebra)
Abstract

We prove that, for ... the operator ... admits realizations generating analytic semigroups in Lp(RN). Moreover, for α < p-N/p, we provide an explicit description of the domain. [ABSTRACT FROM AUTHOR]

Metafune, Giorgio, Sobajima, Motohiro, and Spina, Chiara

Subjects
*ELLIPTIC operators, *PARTIAL differential operators, *HYPOELLIPTIC operators, *DIFFERENTIAL operators, *COEFFICIENTS (Statistics)
Abstract

We show an abstract method to construct different realizations of abstract operators generating a strongly continuous semigroup and apply it to several second order elliptic operators with singular coefficients. [ABSTRACT FROM AUTHOR]
