Capacitary density and removable sets for Newton-Sobolev functions in metric spaces

Panu Lahti

In a complete metric space equipped with a doubling measure and supporting a -Poincaré inequality, we show that every set satisfying a suitable capacitary density condition…

Quasiconformal, Lipschitz, and BV mappings in metric spaces

Panu Lahti

Consider a mapping between two metric measure spaces. We study generalized versions of the local Lipschitz number , as well as of the distortion nu…

Absolutely continuous mappings on doubling metric measure spaces

Panu Lahti, Xiaodan Zhou

Following Malý's definition of absolutely continuous functions of several variables, we consider -absolutely continuous mappings between a doubling metric measu…

On rough traces of BV functions

Panu Lahti

In metric measure spaces, we study boundary traces of BV functions in domains equipped with a doubling measure and supporting a Poincaré inequality, but possibly having a very larg…

Quasiconformal and Sobolev mappings in non-Ahlfors regular metric spaces

Panu Lahti, Xiaodan Zhou

We show that a mapping satisfying the metric condition of quasiconformality outside suitable exceptional sets is in the Newton-Sobolev class $N_{\textrm{loc}}^{1,1…

A note on indecomposable sets of finite perimeter

Panu Lahti

Bonicatto--Pasqualetto--Rajala (2020) proved that a decomposition theorem for sets of finite perimeter into indecomposable sets, known to hold in Euclidean spaces, holds also in co…
