Primitivity testing in free group algebras via duality
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract Let K$K$ be a field and F$F$ a free group. By a classical result of Cohn and Lewin, the free group algebra KF$K\left[F\right]$ is a free ideal ring (FIR): a ring over which the submodules of free modules are themselves free, and of a well‐defined rank. Given a finitely generated right ideal I⩽KF$I\leqslant K\left[F\right]$ and an element f∈I$f\

Isotopy and equivalence of knots in 3‐manifolds
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract Two knots K$K$ and J$J$ in S3$S^3$ are isotopic if and only if they are related by an orientation‐preserving diffeomorphism of S3$S^3$. This claim follows from the fact that any orientation‐preserving self‐diffeomorphism of S3$S^3$ is isotopic to the identity. We show that this same idea applies to any prime oriented closed 3‐manifold.

Coulomb branch algebras via symplectic cohomology
Journal of Topology, Volume 19, Issue 2, June 2026.Abstract Let (M¯,ω)$(\bar{M}, \omega)$ be a compact symplectic manifold with convex boundary and c1(TM¯)=0$c_1(T\bar{M})=0$. Suppose that (M¯,ω)$(\bar{M}, \omega)$ is equipped with a convex Hamiltonian G$G$‐action for some connected, compact Lie group G$G$.

A quel âge les enfants ont-ils l'intuition du caractère transitif ou intransitif des énoncés ?
, 1982 If the functional distinction between transitive and intransitive is made very early, the processes used to express it through language seem to be mastered later. The purpose of this research is to find at what age children acquire this ability. 120 3-to-

Recubrimientos k-arco transitivos de digrafos
, 2001 Un digrafo o grafo dirigido se dice que es k-arco transitivo si tiene grupo de automorfismos que actúa transitivamente en el conjunto de k-arcos. Para un entero positivo k, un k-arco de un digrafo es una secuencia (x0,x1,.,xk) de k+1 vértices del ...

LOCALITY OF CONNECTIVE CONSTANTS, II. CAYLEY GRAPHS
, 2020 . The connective constant µ(G) of a transitive graph G is the exponential growth rate of the number of self-avoiding walks from a given origin. In earlier work of Grimmett and Li, a locality theorem was proved for connective constants, namely, that the ...

Finite groups with H-subgroups or strongly closed subgroups
, 2012 Let G be a finite group. Goldschmidt, Flores and Foote investigated the following concept: A subgroup A of S is said to be strongly closed in S with respect to G if for every a is an element of A, every element of S that is fused in G to a lies in a(G ...

The normal range: a concept in transition.
Archives of pathology & laboratory medicine, 1977 One of the most frequent and perhaps frustrating questions the pathologist is called on to answer regarding laboratory tests is, "What is normal?" In recent years the term "normal range" has been replaced by "reference range." "Upper limit of normal" has been replaced by "referent value," "critical value," or "cut-off point." Our literature now ...
