Automatic Continuity of Almost $n$-Multiplicative Linear Functionals [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2022
We generalize a theorem due to Jarosz, by proving that every almost $n$-multiplicative linear functional on Banach algebra $A$ is automatically continuous.

Automatic Continuity of Almost Derivations on Frechet $Q$-Algebras

open access: yesCommunications in Advanced Mathematical Sciences, 2022
In 1971 R. L. Carpenter proved that every derivation on a semisimple commutative Frechet algebra with identity is continuous. The concept of almost derivations on Frechet algebras is introduced in this article. Also, R. L.

Pettis property for Polish inverse semigroups

open access: yesApplied General Topology, 2023
We study a property about Polish inverse semigroups similar to the classical theorem of Pettis about Polish groups. In contrast to what happens with Polish groups, not every Polish inverse semigroup have the Pettis property.

On an Approximate Solution to Rodriguez Conjecture [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2006
Rickart Theorem ensures the automatic continuity of a dense range homomorphism from a Banach algebra into a strongly Semisimple Banach algebra. Rodriguez conjecture is an extension of Rickart theorem in order to include the nonassociative algebras as ...

Joint Continuity of Bi-multiplicative Functionals [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2021
For Banach algebras $\mathcal{A}$ and $\mathcal{B}$, we show that if $\mathfrak{A}=\mathcal{A}\times \mathcal{B}$ is unital, then each bi-multiplicative mapping from $\mathfrak{A}$ into a semisimple commutative Banach algebra $\mathcal{D}$ is jointly ...

How can the transition from conventional to automatic measurements affect the climatological normals? – A case study from an alpine meteorological observatory at Skalnaté Pleso, Slovakia

open access: yesMeteorologische Zeitschrift, 2023
Harmonizing automatic with conventional meteorological measurements is essential to ensure continuity and homogeneity of long-term climate observations when considering the transition from manual (conventional) to automatic measurement regimes.

SGCN: A multi-order neighborhood feature fusion landform classification method based on superpixel and graph convolutional network

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2023
To address key issues with traditional landform classification methods that impact the integrity and continuity of the analysis area, as well as neglecting neighboring features, We presents a novel approach called superpixel-based graph convolutional ...

Canal-Net for automatic and robust 3D segmentation of mandibular canals in CBCT images using a continuity-aware contextual network

open access: yesScientific Reports, 2022
The purpose of this study was to propose a continuity-aware contextual network (Canal-Net) for the automatic and robust 3D segmentation of the mandibular canal (MC) with high consistent accuracy throughout the entire MC volume in cone-beam CT (CBCT ...
