Holomorphic disks and tropical Lagrangians

Chris T. Woodward · 2026

We develop a calculus for counting pseudoholomorphic disks with boundary in tropical Lagrangians contained in almost toric manifolds, using our previous work with Venugopalan. The results are mostly i…

Excess logarithmic residues for foliations by curves and applications

Alana Cavalcante, Mauricio Correa, Fernando Lourenco, Elaheh Shahsavaripour · 2026

We introduce excess logarithmic residues for one-dimensional holomorphic foliations tangent to a divisor. They arise from the comparison between the logarithmic normal sheaf and the ordinary normal sh…

On the meagerness of the set of irregular bundles on Hopf surfaces

Edoardo Ballico, Elizabeth Gasparim · 2026

Let $\mathcal M_{r,c}$ denote the moduli space of stable bundles with rank $r$ and second Chern class $c>0$ on a Hopf surface. We prove that the subset of $\mathcal M_{r,c}$ formed by irregular bundle…

Total absolute curvature and rigidity of surfaces in Cartan-Hadamard manifolds

Mohammad Ghomi, Joseph Ansel Hoisington, Matteo Raffaelli, John Ioannis Stavroulakis · 2026

We show that closed surfaces with minimal total absolute curvature in Cartan-Hadamard 3-manifolds bound flat convex bodies. This generalizes Chern-Lashof's theorem for surfaces in Euclidean space and …

Contact flexibility and rigidity for toric Gorenstein prequantizations and Ehrhart theory of toric diagrams

Miguel Abreu, Leonardo Macarini, Antonio Rocha-Neves · 2026

Gorenstein toric contact manifolds are good toric contact manifolds with zero first Chern class that are completely determined by certain integral convex polytopes called toric diagrams. The Ehrhart p…

On the Calabi estimate of geometric flows of Hermitian metrics

Marco Gallo, Luigi Vezzoni · 2026

We establish a general result ensuring a $C^1$ a priori bound for smooth curves of Hermitian metrics. As a main application, we obtain a new regularity result for Hermitian curvature flows, and in par…

Geometry of the Donaldson-Friedman Pushout: Twistor degenerations and instanton charge

Amedeo Altavilla, Mauricio Correa · 2026

We study the singular central fibre arising in the Donaldson-Friedman construction for twistor spaces of connected sums, viewing it as a Ferrand pushout of two blown-up twistor spaces along the except…

On the Chern-Ricci form of a twisted almost K\"{a}hler structure

David N. Pham, Fei Ye · 2026

Let $(M,g,J,\omega)$ be an almost K\"{a}hler manifold. For any smooth function $f$ on $M$, one can associate an automorphism $\psi\in \mbox{Aut}(TM)$ for which the K\"{a}hler form is invariant. Using …
