A Hahn-Jordan decomposition and Riesz-Frechet representation theorem in Riesz spaces
, 2022 We give a Hahn-Jordan decomposition in Riesz spaces which generalizes that of [{{\sc B. A. Watson}, {An And\^o-Douglas type theorem in Riesz spaces with a conditional expectation,} {\em Positivity,} {\bf 13} (2009), 543 - 558}] and a Riesz-Frechet ...

On I-Fréchet-Urysohn spaces and sequential I-convergence groups [PDF]
Mathematica Moravica, 2019 In this paper, we introduce the concept of sequential I-convergence spaces and I-Fréchet-Urysohn space and study their properties. We give a sufficient condition for the product of two sequential I-convergence spaces to be a sequential I-convergence ...

Asymptotic Almost Periodic Functions with Range in a Topological Vector Space
Journal of Function Spaces and Applications, 2013 The notion of asymptotic almost periodicity was first introduced by Fréchet in 1941 in the case of finite dimensional range spaces. Later, its extension to the case of Banach range spaces and locally convex range spaces has been considered by several ...

Robust Bernoulli Mixture Models for Credit Portfolio Risk
Mathematical Finance, Volume 36, Issue 3, Page 528-543, July 2026.ABSTRACT This paper presents comparison results and establishes risk bounds for credit portfolios within classes of Bernoulli mixture models, assuming conditionally independent defaults that are stochastically increasing in a common risk factor. We provide simple and interpretable conditions on conditional default probabilities that imply a comparison ...

On Universal Schauder Bases in Non-Archimedean Frechet Spaces [PDF]
, 2004 We prove that there exists a non-archimedean Frechet space U with a basis $(u_n)$ such that any basis $(x_n)$ in a non-archimedean Frechet space X is equivalent to a subbasis $(u_k_n)$ of $(u_n)$.

Frechet-Urysohn property of quasicontinuous functions
, 2023 The aim of this paper is to study the Frechet-Urysohn property of the space $Q_p(X,\mathbb{R})$ of real-valued quasicontinuous functions, defined on a Hausdorff space $X$, endowed with the pointwise convergence topology.

Substantial Diel Changes of Cloud Adjustments to Aerosols in Ship‐Tracks
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Clouds adjust their albedo, amount and liquid water path to anthropogenic aerosols, and produce a climate forcing. Such cloud adjustments are complex functions of both environmental conditions and interaction time. However, direct observations of temporal changes in cloud adjustments are limited. Here, we develop a method to show observational

Seismic Evidence for Slab Tearing Beneath the Indo‐Myanmar Subduction Zone
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Slab tearing has been increasingly recognized as a key geodynamic process influencing the evolution of the eastern Himalayan syntaxis. However, whether, where and how the subducted Indian slab beneath the Indo‐Myanmar subduction zone has been torn remains poorly constrained.

On the Temporal Variability of Precipitation in Iraq: Arid‐Wet Years and Extreme Events
International Journal of Climatology, Volume 46, Issue 7, 15 June 2026.Daily and monthly precipitation data in Iraq display high seasonal to interdecadal variability, with arid and wet years that have very distinct seasonal cycles. Monthly rainfall is significantly correlated with the Indian Ocean Dipole. Extreme events are identified and classified as belonging to four different weather patterns, allowing to obtain daily

Frechet differentiability in Besov spaces in the optimal control of parabolic free boundary problems
, 2017 We consider the inverse Stefan type free boundary problem, where information on the boundary heat flux and the density of the sources are missing and must be found along with the temperature and the free boundary.
