Regularity of conservative inductive limits

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
A sequentially complete inductive limit of Fréchet spaces is regular, see [3]. With a minor modification, this property can be extended to inductive limits of arbitrary locally convex spaces under an additional assumption of conservativeness.

Fréchet spaces of continuous vector-valued functions: Complementability in dual Fréchet spaces and injectivity [PDF]

open access: yes, 1992
Fréchet spaces of strongly, weakly and weak*-continuous Fréchet space valued functions are considered. Complete solutions are given to the problems of their injectivity or embeddability as complemented subspaces in dual Fréchet ...

A Smoothing Property for Fréchet Spaces [PDF]

open access: yes, 1996
A smoothing property (SΩ)tfor Fréchet spaces is introduced generalizing the classical concept of smoothing operators which are important in the proof of Nash–Moser inverse function theorems. For Fréchet–Hilbert spaces property (Ω) in standard form in the

Synthetic Imagery Improves Ecological Classification When Real Data Are Scarce, Not Direct Substitutes

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Image generation models can create synthetic ecological datasets and potentially alleviate limitations from sparse real data. Using 20 tree genera across community‐science and street‐view imagery, we tested whether synthetic images could replace or supplement real data for image classification.

Spaces Fréchet–Urysohn with respect to families of subsets [PDF]

open access: yes, 2002
The study of the Fréchet–Urysohn property with respect to a family of subsets started by Reznichenko and this author in relation to the problem of Malykhin on the existence in ZFC of a separable nonmetrizable Fréchet–Urysohn topological group is ...

World Models for Robotic Manipulation: A Survey

open access: yesSmartBot, EarlyView.
World models enable robots to anticipate how candidate actions may alter object configurations, contact states, and scene geometry before physical execution. This survey examines world models for robotic manipulation as action‐conditioned predictive systems and organizes the literature according to predicted representations, interfaces between ...

Leray-Schauder results for multivalued nonlinear contractions defined on closed subsets of a Fréchet space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
New Leray-Schauder results are presented for multivalued contractions defined on subsets of a Fréchet space E. The proof relies on fixed point results in Banach spaces and on viewing E as the projective limit of a sequence of Banach spaces.

Recent advances in polymeric chemically amplified positive resists: Materials and design strategies

open access: yesSmart Molecules, EarlyView.
This review summarizes recent advances in the molecular design of positive chemically amplified resists, focusing on photoacid generators and polymer architectures. Key strategies for enhancing sensitivity—including self‐amplification effects, copolymerization of sensitive monomers, controlled polymerization, and photosensitized chemically amplified ...

Quasi-reflexive Fréchet spaces and mean ergodicity [PDF]

open access: yes, 2010
We characterize quasi-reflexive Fréchet spaces with a basis in terms of the properties of this basis. As a consequence we prove that a Fréchet space with a basis is quasi-reflexive of order one if and only if for every power bounded operator T, either T ...
