We study minimizers of non-autonomous functionals $ \begin{align*} \inf\limits_u \int_\Omega \varphi(x,|\nabla u|) \, dx \end{align*} $ when $ \varphi $ has generalized Orlicz growth. We consider the case where the upper growth rate of $ \varph

Abstract Background In this cross-national study, Spanish, Finnish, and Swedish middle and high school students’ procedural flexibility was examined, with the specific intent of determining whether and how students’ equation-solving accuracy and

In this paper basic properties of both Sobolev and relative capacities are studied in generalized Orlicz spaces. The capacities are compared with each other and the Hausdorff measure. As an application, the existence of quasicontinuous representative

We prove higher integrability of the spatial gradient of weak solutions to parabolic systems with $\phi$-growth, where $\varphi=\varphi(t)$ is a general Orlicz function. The parabolic systems need be neither degenerate nor singular. Our result is a g

Anisotropic generalized Orlicz spaces have been investigated in many recent papers, but the basic assumptions are not as well understood as in the isotropic case. We study the greatest convex minorant of anisotropic $\Phi$-functions and prove the equ

We establish maximal local regularity results of weak solutions or local minimizers of \[ \operatorname{div} A(x, Du)=0 \quad\text{and}\quad \min_u \int_\Omega F(x,Du)\,dx, \] providing new ellipticity and continuity assumptions on $A$ or $F$ with ge

To secure a bright future for Finland, more students who are interested in mathematics, science and technology (STEM) subjects are needed. To make this possible, training motivated and talented teachers, and improving education research, play a key r

In this paper we present a design experiment on a continued professional development (CPD) course for mathematics teachers. It consisted of three teaching cycles. Between them we analyzed the collected data in order to discover the factors affecting
