Higher order div-curl type estimates for elliptic linear differential operators on localizable Hardy spaces
Catarina Machado, Tiago Picon
In this work, we establish higher-order div-curl type estimates in the sense of Coifman, Lions, Meyer & Semmes, in a local setting for elliptic homogeneous linear differential oper…

Nonhomogeneous div-curl type estimates for system of complex vector fields on local Hardy spaces
Catarina Machado, Tiago Picon
In this work, we present a nonhomogeneous version of the classical div-curl type estimates in the setup of elliptic system of complex vector fields with constant coefficients on lo…
