Statistical Limit Theorems for Axiom A Diffeomorphisms: Exponential Mixing, Central Limit Theorem, and Large Deviations

Abdoulaye Thiam · 2026

We establish statistical limit theorems for equilibrium states of Axiom A diffeomorphisms, derived from the spectral gap of the Ruelle transfer operator established in Part I (Thiam2026a) and transfer…

The Instrumental Dissolution of Typing: Why AI Challenges the Keyboard Era in Knowledge Work

Wei Roy Hua · 2026

For four decades, the QWERTY keyboard organized white-collar knowledge work. Typing's dominance was instrumental, not cognitively necessary. As multimodal AI achieves human-parity understanding of spe…

Beyond the Critical Depth: The Metabolic and Physical Drivers of Phytoplankton Persistence in a Changing Ocean

Matias Neto, Pablo Marquet (PUC, CMM), Mara Freilich, Luis Marti, Nayat Sanchez-Pi · 2026

While the classical Critical Depth Hypothesis (CDH) effectively explains the onset of blooms as transient instabilities, it does not fully capture the seasonal decoupling of biological rates and the l…

Why MLLMs Struggle to Determine Object Orientations

Anju Gopinath, Nikhil Krishnaswamy, Bruce Draper · 2026

Multimodal Large Language Models (MLLMs) struggle with tasks that require reasoning about 2D object orientation in images, as documented in prior work. Tong et al. and Nichols et al. hypothesize that …

Universal statistical signatures of evolution in artificial intelligence architectures

Theodor Spiro · 2026

We test whether artificial intelligence architectural evolution obeys the same statistical laws as biological evolution. Compiling 935 ablation experiments from 161 publications, we show that the dist…

Social Reality Construction via Active Inference: Modeling the Dialectic of Conformity and Creativity

Kentaro Nomura, Takato Horii · 2026

Social agents both internalize collective norms and reshape them through creative action, yet computational models have not captured this bidirectional process within a unified framework. We propose a…

On Petr Novikov's problem of ordered systems of uniform sets

Vladimir Kanovei, Vassily Lyubetsky · 2026

We prove that every ordinal $\alpha<\omega_2$ is the order type of a certain system of uniform Borel sets in the sense of a well-ordering relation defined by Petr Novikov. This result gives a positive…

CVT Archives and Chemical Embedding Measures for Multi-Objective Quality Diversity in Molecular Design

Dominic Mashak, Jacob Schrum · 2026

Nonlinear optical (NLO) materials are essential for photonic technologies, yet discovering optimal NLO molecules requires balancing multiple competing objectives across vast chemical spaces. Previous …

A graph based advection framework for climate-driven species distribution

Pranali Roy Chowdhury, Soumyendu Raha · 2026

Climate change is reshaping species interactions and movement across fragmented landscapes. Despite this, most mathematical models assume random diffusion, overlooking the influence of directed moveme…

Kernel Dynamics under Path Entropy Maximization

Jnaneshwar Das · 2026

We propose a variational framework in which the kernel function k : X x X -> R, interpreted as the foundational object encoding what distinctions an agent can represent, is treated as a dynamical vari…

Ecological systems in a modeling perspective

Torsten Lindstrom · 2026

May (1974,1976) opened the debate on whether biological populations might exhibit nonlinear dynamics and chaos. However, it has in general been difficult to verify nonlinear dynamics in biological pop…

Cities cluster into growth regimes that propagate shocks

Isaak Mengesha, Debraj Roy · 2026

Economic growth is conventionally analyzed at the national level, yet cities generate the bulk of global output. Here we construct GDP trajectories for 8,808 functional urban areas (FUAs) across 165 c…

Stability of the generalized Wehrl entropy and the local concentration of homogeneous polynomials

Maria Angeles Garcia-Ferrero, Joaquim Ortega-Cerda · 2026

We study two notions of concentration for homogeneous polynomials of degree $N$ in $d+1$ complex variables on the unit sphere: a local notion measuring the fraction of the $L^2$-norm supported on a me…
