Articles in Finnish published in Solmu, a Finnish math magazine mainly aimed at high school students:
Rekonstruktiokonjektuuri verkkoteoriassa. The article is about the reconstruction conjecture in graph theory.
Miksei funktiota e^{-x^2} voi integroida? (Osa 1) - (Osa 2) The article is about the fact that some elementary functions, like the famous bell-shaped e^{-x^2}, do not have elementary antiderivatives. The first part (Osa 1) contains the necessary tools to state Liouville's theorem. The second part (Osa 2) presents a long proof of this theorem, starting from standard tools in algebra and analysis.
