Weakly compactly generated Frechet spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
It is proved that a weakly compact generated Frechet space is Lindelöf in the weak topology. As a corollary it is proved that for a finite measure space every weakly measurable function into a weakly compactly generated Frechet space is weakly equivalent

On asymptotically normable Fréchet spaces

open access: yes, 1991
Let E be a Fréchet space, $\| \;\|_1≤ \|\;\| ≤ \ldots $ a fundamental system of seminorms on E and U, $ Uk= {x∈ E: \|x\|_k≤ 1}$ for every k. E is called asymptotically normable, if there is a $k0$, such that for every $k ≥ k0$, there is a p so that the ...

Spatial and Temporal Patterns of Extreme Hourly Rainfall in the Hawaiian Islands

open access: yesInternational Journal of Climatology, EarlyView.
The extreme rainfall trends in Hawaiʻi were revealed by hourly rainfall data: Across islands, Kauaʻi and Hawaiʻi Island had larger events at a return period. Annual maximum series of 15 gauges showed significant positive trends. While extreme rainfall trends show increases or decreases regionally, the trends varied with rainfall duration.

Quasi-bounded sets

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
It is proved in [1] & [2] that a set bounded in an inductive limit E=indlim En of Fréchet spaces is also bounded in some En iff E is fast complete. In the case of arbitrary locally convex spaces En every bounded set in a fast complete indlim En is quasi ...

Stability of the Fréchet Equation in Quasi-Banach Spaces

open access: yesMathematics, 2020
We investigate the Hyers–Ulam stability of the well-known Fréchet functional equation that comes from a characterization of inner product spaces. We also show its hyperstability on a restricted domain. We work in the framework of quasi-Banach spaces.

Diametral dimensions of Fréchet spaces

open access: yes, 2016
peer reviewedThis article provides new results concerning the equality between two diametral dimensions. It shows that this equality is true for hilbertizable Fréchet-Schwartz spaces.

High‐Fidelity Synthetic Raman Spectra Generation for Sinter Basicity Prediction Using β$$ \beta $$‐Variational Autoencoders

open access: yesJournal of Raman Spectroscopy, EarlyView.
A β$$ \beta $$‐variational autoencoder with β$$ \beta $$ = 0.1 generates high‐fidelity synthetic Raman spectra of industrial sinter with a 16‐fold improvement in spectral fidelity over SMOTE‐based augmentation (KL divergence: 0.0075 vs. 0.121), enabling reliable basicity prediction (R2 = 0.83) from limited labeled datasets.

Nonlinear operators between neutrosophic normed spaces and Fréchet differentiation

open access: yesJournal of Inequalities and Applications, 2022
The article focuses on the introduction of neutrosophic continuity and neutrosophic boundedness, which is a fair extension of intuitionistic fuzzy continuity and intuitionistic fuzzy boundedness, respectively.

Optimal Design of Elastic Plates: Hybrid Numerical Method Based on Homogenization and Shape Derivative

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper focuses on optimal design problems in the context of the Kirchhoff‐Love model for pure bending of a thin, solid, symmetric plate under a transverse load. The objective is to simultaneously determine the optimal outer shape of the domain and the distribution of two isotropic materials within the domain in order to minimize compliance.

Fragmentation–Coagulation Processes With Advection or Diffusion in Space

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a continuous fragmentation–coagulation model in which the reacting particles can be transported in physical space through either advection or diffusion. We prove new results on the generation of C0$$ {C}_0 $$‐semigroups with parameter and use them to show that the abstract Cauchy problem associated with a more ...
