Hva slags fagbevegelse trenger vi?
1.
En fri fagbevegelse må for det fŸrste definere sine primæroppgaver. Med dette menes at vi må bestemme oss for hva som er fagbevegelsens viktigste felt på kort og lang sikt. Det er klart at kampen for en lŸnn å leve av, trygge ansettelsesvilkår og en arbeidstid som lar seg forene med et sunt sosialt liv, familiemessig og på andre måter er viktige. Kampen for arbeids­plassene og solidariteten med, og organiseringen av de arbeidslŸse hŸrer klart…

Exotic diffeomorphisms on a contractible 4-manifold surviving two stabilizations
We develop a $\mathrm{Pin}(2) \times \mathbb{Z}_2$-equivariant refinement of the lattice homotopy type for computing equivariant Seiberg--Witten Floer homotopy types. As an application, we construct a relatively exotic diffeomorphism on a compact contractible 4-manifold that survives two stabilizations.

t3n analysiert OpenAIs Versuch, politische Voreingenommenheit zu neutralisieren. Beeindruckend: GPT‑5 reagiert „30 % objektiver“. Beunruhigend: Gleichzeitig definiert Präsident Trump, was „zu woke“ ist. Wenn Politik vorgibt, wie Unparteilichkeit auszusehen hat, bleibt von Neutralität nur der Algorithmus | t3n #ChatGPT

On dynamical invariants of coadjoint orbits of 3D volume-preserving diffeomorphisms
The helicity, or asymptotic linking number, is a functional of exact volume-preserving vector fields on 3-manifolds, invariant under volume-preserving transformations. It is known to exhibit remarkable uniqueness properties: many invariant functionals reduce to functions of helicity. We examine how severely this uniqueness can fail. On integral homology spheres with the $C^{1}$-topology, the failure is extreme: for every $C^{1}$-open set of nonvanishing exact fields of fixed helicity, some othe…

On absolutely exotic diffeomorphisms of 4-manifolds
We prove that there exist infinitely many contractible compact smooth $4$-manifolds $C$ that admit absolutely exotic diffeomorphisms of infinite order in $π_0(\mathrm{Diff}(C))$. By ``absolutely", we mean that isotopies are not required to be relative to the boundary. This follows from a theorem that produces absolutely exotic diffeomorphisms from relatively exotic diffeomorphisms, analogous to a theorem of Akbulut and Ruberman that produces absolutely exotic 4-manifolds from relatively exotic…

On the plaque topological stability of partially hyperbolic diffeomorphisms
We prove that every dynamically coherent plaque expansive partially hyperbolic diffeomorphism is topologically stable with respect to the central foliation (in short, {\em plaque topologically stable}). Next, we study partially hyperbolic diffeomorphisms that are both expansive and topologically stable with respect to a central foliation. We show that the center chain recurrent set for such diffeomorphisms belongs to the closure of the center periodic points.
