Pinwheels in symplectic rational and ruled surfaces and non‐squeezing of rational homology balls

open access: yesJournal of Topology, Volume 19, Issue 3, September 2026.
Abstract We use almost toric fibrations and the symplectic rational blow‐up to determine when certain Lagrangian pinwheels, which we call liminal, embed in symplectic rational and ruled surfaces. The case of L2,1$L_{2,1}$‐pinwheels, namely Lagrangian RP2s$\mathbb {R}P^2{\rm s}$, answers a question of Kronheimer in the negative, exhibiting a symplectic ...

Finite abelian group actions on weakly Lefschetz cohomologically symplectic manifolds

open access: yesJournal of Topology, Volume 19, Issue 3, September 2026.
Abstract We study continuous finite abelian group actions on weakly Lefschetz cohomologically symplectic (WLS) manifolds, a collection of topological manifolds that includes all compact connected Kaehler manifolds. We prove that for any WLS manifold X$X$, there exists a number C$C$ such that, for any integer m⩾C$m\geqslant C$, if (Z/m)k$({\mathbb {Z ...

Invariant splitting principles for the Lipshitz–Ozsváth–Thurston correspondence

open access: yesJournal of Topology, Volume 19, Issue 3, September 2026.
Abstract We prove that the Lipshitz–Ozsváth–Thurston correspondence between extended type D structures of knot complements and F[U,V]/(UV)$\mathbb{F}[U,V]/(\textit{UV})$ knot Floer complexes can be arranged so that ιK${\iota}_{K}$‐invariant splittings of knot Floer chain complexes correspond to ιS3∖K${\iota}_{{S}^{3}\setminus K}$‐invariant splittings ...

Simple groups and complements of smooth surfaces in simply connected 4‐manifolds

open access: yesJournal of Topology, Volume 19, Issue 3, September 2026.
Abstract For each integer n$n$ we construct an oriented closed simply connected 4‐manifold X$X$ admitting a smoothly embedded closed connected surface Σ$\Sigma$ of self‐intersection number n$n$ such that the complement of the surface has non‐trivial fundamental group. This answers a question of Kronheimer in Kirby's 1997 problem list.

Pacific Warming Pattern Discrepancy Linked to Spurious Rainband in Climate Models

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The distinctive pattern of observed Pacific surface temperature trends, with cooling in the east and intensified warming in the west, departs from the more uniform warming anticipated by climate models. The apparent inability of climate models to simulate this warming pattern limits our ability to understand why it is occurring and to predict ...
