The presence of zeroes in Compositional Data (CoDa) is a thorny issue for Aitchison’s classical log-ratio analysis. Building upon the geometric approach by Faugeras (2023), we study the full CoDa simplex from the perspective of affine geometry. This view allows to regard CoDa as points (and not...

This paper investigates the exit-time problem for time-inhomogeneous diffusion processes. The focus is on the small-noise behavior of the exit time from a bounded positively invariant domain. We demonstrate that, when the drift and diffusion terms are uniformly close to some time-independent...
