- We consider the Cohen-Macaulay compactification of the space of twisted cubics in Pn. This compactification is the fine moduli scheme representing the functor of CM-curves with Hilbert polynomial 3t + 1. We show that the moduli scheme of CM-curves in P3 is isomorphic to the twisted cubic component of the Hilbert scheme. We also describe the compactification for twisted cubics in Pn

- Dans cet article on obtient un théorème du type Bochner-Godement pour des algèbres commutatives involutives et avec unité et puis on applique ce théorème pour obtenir des résolutions pour le problème des moments sur les polydisques et les polyrectangles de S (où S est un semi-groupe abélien avec involution et élément neutre) et sur certains de leurs sous-ensembles.

Konferensbidrag (refereegranskat)abstract
- The paper presents the synthesis of a series of studies on support measures for pupils with additional languages in Sweden, with a particular focus on the consequences of language support measures for teaching and learning school mathematics. The analysis identifies several critical aspects in mathematics teaching when the pupils transition from one school system to another, and particularly when they do not yet have a shared language to communicate among each other or with their teachers. Three aspects with relevance to language support will be discussed and illustrated with examples from the studies: the notion of mathematics as a formal language; the notion of levels and absolute progression in mathematics; the notion that learning mathematics means understanding "concepts".
