Topology, 1967 Abstract : A map of countable CW-complex into a topological group is discussed regarding its homotopy-commutative properties. Proofs are offered for six theorems with correlaries and lemmas. ad-259 8779N6 AD-259 878Div. 26, 17, 1 (21 July 61) Ministry of AviaAD-259 878Div. 26, 17, 1 (21 July 61) Ministry of Aviation (Gt.

Finite models for positive combinatorial and exponential algebra
Bulletin of the London Mathematical Society, EarlyView.Abstract We use high girth, high chromatic number hypergraphs to show that there are finite models of the equational theory of the semiring of non‐negative integers whose equational theory has no finite axiomatisation, and show this also holds if factorial, fixed base exponentiation and operations for binomial coefficients are adjoined.

Bulletin of the London Mathematical Society, EarlyView.Abstract We prove that (under appropriate orientation assumptions), the action of a Hamiltonian homeomorphism ϕ$\phi$ on the cohomology of a relatively exact Lagrangian fixed by ϕ$\phi$ is the identity. This extends results of Hu–Lalonde–Leclercq [Geom. Topol. 15 (2011), no. 3, 1617–1650] and the author [Selecta Math. (N.S.) 30 (2024), no. 2, Paper No.

Arithmetic sparsity in mixed Hodge settings
Bulletin of the London Mathematical Society, EarlyView.Abstract Let X$X$ be a smooth irreducible quasi‐projective algebraic variety over a number field K$K$. Suppose X$X$ is equipped with a p$p$‐adic étale local system compatible with an admissible graded‐polarized variation of mixed Hodge structures on the complex analytification of XC$X_{\operatorname{\mathbb {C}}}$.

Scissors congruence K$K$‐theory for equivariant manifolds
Bulletin of the London Mathematical Society, EarlyView.Abstract We introduce a scissors congruence K$K$‐theory spectrum that lifts the equivariant scissors congruence groups for compact G$G$‐manifolds with boundary, and we show that on π0$\pi _0$, this is the source of a spectrum‐level lift of the Burnside ring‐valued equivariant Euler characteristic of a compact G$G$‐manifold.

Explicit constructions of short virtual resolutions of truncations
Bulletin of the London Mathematical Society, EarlyView.Abstract We propose a concept of truncation for arbitrary smooth projective toric varieties and construct explicit cellular resolutions for nef truncations of their total coordinate rings. We show that these resolutions agree with the short resolutions of Hanlon, Hicks, and Lazarev, which were motivated by symplectic geometry, and we use our definition

The commuting distribution [PDF]
, 2004 In this paper we analyse the commuting distribution from a job search perspective. We have examined under which conditions the commuting distribution is unimodal which is one of the stylised facts of commuting. It appears that a necessary condition is that space is two-dimensional. Furthermore, one of the following ingredients is sufficient: on-the-job
