Ramsey Property and Pathological Sets: Almost Disjointness, Independence and Other Maximal Objects

Jialiang He, Jintao Luo, Shuguo Zhang · 2026

We show that under $\mathsf{ZF} + \mathsf{CC}_{\mathbb R}$, if the Ramsey property holds for all sets in a good pointclass $\Gamma$, then there is no MAD family in $\Gamma$, proving a long-standing co…

From lab to outbreak: experimental mosquito extrinsic incubation period distributions shape dengue epidemic dynamics

Lea Loisel, Sandie Arnoux, Gael Beaunee, Pauline Ezanno · 2026

Dengue virus transmission models commonly assume an exponential distribution for the mosquito extrinsic incubation period (EIP), potentially oversimplifying biological variability. We developed a stoc…

Leverage Laws: A Per-Task Framework for Human-Agent Collaboration

Stan Loosmore · 2026

We propose a per-task leverage ratio for human-agent collaboration: human work displaced by an agent, divided by the human time required to specify the task, resolve mid-run interrupts, and review the…

SUDA-Muon: Structural Design Principles and Boundaries for Fully Decentralized Muon

Hengrui Zhang, Boao Kong, Jiahe Geng, Zhengyang Huang · 2026

Fully decentralized Muon is difficult because its nonlinear matrix-sign operator does not commute with linear gossip averaging. This makes decentralized Muon a structural design problem: in designing …

Malliavin calculus for signatures with applications to finance

Eduardo Abi Jaber, Clement Rey, Dimitri Sotnikov · 2026

Malliavin calculus is a powerful and general framework for the analysis of square-integrable random variables, but it often suffers from a lack of tractability and explicit representations. To address…

Composition operators and Rational Inner Functions on the bidisc: A geometric approach

Athanasios Beslikas · 2026

We study composition operators acting on the weighted Bergman spaces on the bidisc, i.e. $C_{\Phi}:A^2_{\beta}(\mathbb{D}^2)\to A^2_{\beta}(\mathbb{D}^2)$ where $\Phi$ is induced by rational inner fun…
