An Approach to Fisher-Rao Metric for Infinite Dimensional Non-Parametric Information Geometry
EntropyNon-parametric information geometry has long faced an “intractability barrier”: in the infinite-dimensional setting, the Fisher–Rao metric is a weak Riemannian metric functional that lacks a bounded inverse, rendering classical optimization and ...

The Pontryagin Forms of Hessian Manifolds [PDF]
, 2016 We show that Hessian manifolds of dimensions 4 and above must have vanishing Pontryagin forms. This gives a topological obstruction to the existence of Hessian metrics. We find an additional explicit curvature identity for Hessian 4-manifolds. By contrast, we show that all analytic Riemannian 2-manifolds are Hessian.

Cointegration in a MIDAS Regression
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT Mixed data sampling (MIDAS) cointegration models are used to analyse variables observed at different frequencies. In this paper, we start from an assumed autoregressive distributed lag (ADL) model for high‐frequency observations, and derive the resulting representation when the dependent variable is only observed at a lower frequency.

Philosophy and Phenomenological Research, EarlyView.ABSTRACT Guessing is the thesis that, roughly put, you may believe something iff it is among the most probable answers to a salient question. The thesis is motivated by observed features of felicitous belief reports when agents confront a question they aren't certain how to answer.

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.Abstract Due to the craft beer industry, there is an emerging need for winter malting barley (Hordeum vulgare L.) nitrogen (N) rate recommendations in Ohio. An experiment was conducted at seven site‐years to identify the optimum spring N application rate to maximize barley grain yield while maintaining protein requirements for malting.

Cross‐Method Explanation Stability Under Prediction‐Preserving Perturbations in Explainable AI
Applied AI Letters, Volume 7, Issue 2, June 2026.The cross‐method analysis showed common vulnerability patterns across gradient‐based and perturbation‐based explainers, whereas Grad‐CAM demonstrated a specific ability to be resilient. Further discussion revealed that, before prediction changes with increasing ε, explanation divergence could already have commenced, indicating that further explanation ...

A fully nonlinear generalized Monge-Ampere PDE on a torus
Electronic Journal of Differential Equations, 2014 We prove an existence result for a "generalized" Monge-Ampere equation, introduced in [11], under some assumptions on a flat complex 3-torus. As an application we prove the existence of Chern connections on certain kinds of holomorphic vector bundles ...
