Cohomotopy sets of (n−1)$(n-1)$‐connected (2n+2)$(2n+2)$‐manifolds for small n$n$

open access: yesTransactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract Let M$M$ be a closed orientable (n−1)$(n-1)$‐connected (2n+2)$(2n+2)$‐manifold, n⩾2$n\geqslant 2$. In this paper, we combine the Postnikov tower of spheres and the homotopy decomposition of the reduced suspension space ΣM$\Sigma M$ to investigate the (integral) cohomotopy sets π*(M)$\pi ^\ast (M)$ for n=2,3,4$n=2,3,4$, under the assumption ...

The contact cut graph and a Weinstein L$\mathcal {L}$‐invariant

open access: yesTransactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract We define and study the contact cut graph which is an analogue of Hatcher and Thurston's cut graph for contact geometry, inspired by contact Heegaard splittings (Giroux, Proceedings of the International Congress of Mathematicians, Beijing, 2002; Torisu, Internat. Math. Res. Notices (2000), 441–454).

Shaping Social Eye Contact in Children With Autism Via Telehealth: A Parent‐Implemented Intervention

open access: yesBehavioral Interventions, Volume 40, Issue 4, November 2025.
ABSTRACT Lack of social eye contact is a common characteristic of autism spectrum disorder (ASD) and can limit opportunities for social interaction and social learning. The current study examined a parent‐implemented shaping procedure delivered through telehealth to promote eye contact during naturalistic social play for two preschool‐aged children ...

On 3‐Designs From P G L ( 2 , q )

open access: yesJournal of Combinatorial Designs, Volume 33, Issue 11, Page 428-432, November 2025.
ABSTRACT The group P G L ( 2 , q ) acts 3‐transitively on the projective line G F ( q ) ∪ { ∞ }. Thus, an orbit of its action on the k‐subsets of the projective line is the block set of a 3‐ ( q + 1 , k , λ ) design. We find the parameters of the designs formed by the orbit of a block of the form 〈 θ r 〉 or 〈 θ r 〉 ∪ { 0 }, where θ is a primitive ...
