Automatic continuity of multiplicative polynomial operators [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
This paper deals with the automatic continuity of multiplicative polynomial operators on a class of topological algebras. Several results are derived in this direction. We also support our results by some examples.

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.

Synthesis of a digital PID controller to control the temperature in the agricultural products drying chamber [PDF]

open access: yesE3S Web of Conferences, 2023
This article provides information and results of measurement and automatic temperature control with a proportional-integral-derivative controller. A microcontroller including special software is used for automatic control the temperature at a given value.

Jewell-Sinclair theorem and the automatic continuity of a derivation [PDF]

open access: yesمجلة التربية والعلم, 2010
Villena's theorem ensure the automatic continuity of a derivation on a non-associative H*-algebra with zero annihilator. In this paper, we formulate the Jewell-Sinclair theorem in a non-associative content, and we show that the Villena's theorem may be ...

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.

The automatic continuity for particular type of homomorphism nonassociative algebras [PDF]

open access: yesمجلة التربية والعلم, 2008
Rodriguez conjecture ensures the automatic continuity of a dense range homomorphism from a complete normed nonassociative algebra into another one with zero strong radical. Rodriguez conjecture still unsolved.

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 ...
