Bloch estimates in non-doubling generalized Orlicz spaces

Petteri Harjulehto, Peter Hästö, Jonne Juusti

We study minimizers of non-autonomous functionals \begin{align*} \inf_u \int_Ωφ(x,|\nabla u|) \, dx \end{align*} when $φ$ has generalized Orlicz growth. We consider the case where…

Extension in generalized Orlicz--Sobolev spaces

Jonne Juusti

We study the existence of an extension operator $Λ : W^{1, φ} (Ω) \to W^{1, ψ} (R^{n})$ . We assume that $φ \in Φ_{w} (Ω)$ has generalized Orlicz growth, $ψ\in Φ_\mathrm{…

Riesz spaces with generalized Orlicz growth

Peter Hästö, Jonne Juusti, Humberto Rafeiro

We consider a Riesz $ϕ$ -variation for functions $f$ defined on the real line when $φ : Ω \times [0, \infty) \to [0, \infty)$ is a generalized $Φ$ -function. We show that it generates a quas…
