It is a well-known fact that in a Lipschitz domain Ω ⊂ R
n
a p-Hardy inequality, with weight dist(x, ∂Ω)β
, holds for all u ∈ C
∞0 (Ω)
whenever β < p − 1. We show that actually the same is true under
the sole assumption that the boundary of the domain satisfies a uniform
density condition with the exponent λ = n − 1. Corresponding results
also hold for smaller exponents, and, in fact, our methods work in general
metric spaces satisfying standard structural assumptions.

Self-improvement of weighted pointwise inequalities on open sets
Eriksson-Bique, Sylvester; Lehrbäck, Juha; Vähäkangas, Antti V. (Elsevier BV, 2020)We prove a general self-improvement property for a family of weighted pointwise inequalities on open sets, including pointwise Hardy inequalities with distance weights. For this purpose we introduce and study the classes ... -
Sharpness of uniform continuity of quasiconformal mappings onto s-John domains
Guo, Changyu; Koskela, Pekka (Suomalainen tiedeakatemia, 2017)We show that a prediction in [8] is inaccurate by constructing quasiconformal mappings onto s-John domains so that the mappings fail to be uniformly continuous between natural distances. These examples also exhibit the ... -
