Double phase image restoration
Petteri Harjulehto, Peter Hästö
In this paper we explore the potential of the double phase functional in an image processing context. To this end, we study minimizers of the double phase energy for functions with…

Higher integrability for parabolic systems with Orlicz growth
Peter Hästö, Jihoon Ok
We prove higher integrability of the spatial gradient of weak solutions to parabolic systems with -growth, where is a general Orlicz function. The parabolic systems nee…

Maximal regularity for local minimizers of non-autonomous functionals
Peter Hästö, Jihoon Ok
We establish local -regularity for some and -regularity for any of local minimizers of the functional \[ v\ \mapsto\ \int_Ωϕ(x,|Dv|)\,dx, \] w…
