Monotone approximation of differentiable convex functions with applications to general minimization problems
Petteri Harjulehto, Peter Hästö, Andrea Torricelli
We study minimizers of non-autonomous energies with minimal growth and coercivity assumptions on the energy. We show that the minimizer is nevertheless the solution of the relevant…
A revised condition for harmonic analysis in generalized Orlicz spaces on unbounded domains
Petteri Harjulehto, Peter Hästö, Artur Słabuszewski
Conditions for harmonic analysis in generalized Orlicz spaces have been studied over the past decade. One approach involves the generalized inverse of so-called weak -functions.…
Convergence of generalized Orlicz norms with lower growth rate tending to infinity
Giacomo Bertazzoni, Petteri Harjulehto, Peter Hästö
We study convergence of generalized Orlicz energies when the lower growth-rate tends to infinity. We generalize results by Bocea--Mihăilescu (Orlicz case) and Eleuteri--Prinari (va…
Strategy flexibility in university mathematics
Peter Hästö, Jon R. Star
We present results and ideas on flexibility and its teaching for university mathematicians based on research and our experience in professional development programs. We believe thi…
Bounded variation spaces with generalized Orlicz growth related to image denoising
Michela Eleuteri, Petteri Harjulehto, Peter Hästö
Motivated by the image denoising problem and the undesirable stair-casing effect of the total variation method, we introduce bounded variation spaces with generalized Orlicz growth…
Regularity theory for non-autonomous problems with a priori assumptions
Peter Hästö, Jihoon Ok
We study weak solutions and minimizers of the non-autonomous problems and with quasi-isotropic -growth. We co…
