Tematy:: *-inverse closed
inverse closed
symmetric Banach *-algebra
Opis:: Let A be a Banach *-algebra which is a subalgebra of a Banach algebra B. In this paper, assuming that A is symmetric, various conditions are given which imply that A is inverse closed in B.

Tytuł:: Convergence in the generalized sense relative to Banach algebras of operators and in LMC-algebras
Autorzy:: Barnes, Bruce A.
Powiązania:: https://bibliotekanauki.pl/articles/1289118.pdf
Data publikacji:: 1995
Wydawca:: Polska Akademia Nauk. Instytut Matematyczny PAN
Tematy:: convergence in the generalized sense
spectral theory
LMC-algebra
Opis:: The notion of convergence in the generalized sense of a sequence of closed operators is generalized to the situation where the closed operators involved are affiliated with a Banach algebra of operators. Also, the concept of convergence in the generalized sense is extended to the context of a LMC-algebra, where it applies to the spectral theory of the algebra.

Tytuł:: Perturbation theory relative to a Banach algebra of operators
Autorzy:: Barnes, Bruce A.
Powiązania:: https://bibliotekanauki.pl/articles/1292602.pdf
Data publikacji:: 1993
Wydawca:: Polska Akademia Nauk. Instytut Matematyczny PAN
Tematy:: Banach algebra of operators
Fredholm operator
perturbation theory
essential spectrum
Opis:: Let ℬ be a Banach algebra of bounded linear operators on a Banach space X. Let S be a closed linear operator in X, and let R be a linear operator in X. In this paper the spectral and Fredholm theory relative to ℬ of the perturbed operator S + R is developed. In particular, the situation where R is S-inessential relative to ℬ is studied. Several examples are given to illustrate the usefulness of these concepts.

Tytuł:: The Noahide Laws and the Universal Fellowship with God
Autorzy:: Barnes, Bruce R.
Powiązania:: https://bibliotekanauki.pl/articles/2149959.pdf
Data publikacji:: 2021
Wydawca:: Uniwersytet w Białymstoku. Wydawnictwo Uniwersytetu w Białymstoku
Tematy:: natural law
Moses Maimonides
he Noahide Laws
lassical Islamic philosophy
ecumenical dialogue
Opis:: This article presents the possibility of a theory of natural law in Judaism from the Jewish perspective by listening to the Jewish tradition of scholarship on religion and philosophy. The first part of this paper is concerned with evidence for a theory of natural law in Judaism. It centers around the Noahide Laws and their influence on Gentile and pre-Simatic Judaism. The second part deals with Moses Maimonides and his ideas concerning the interpretation of natural law for Jews. The third part discusses Jewish scholars who have refuted the work of Maimonides and proposed various theories of natural law. They have been a consistent part of Jewish tradition and provide a path, however narrow, along which Jews may travel towards participation in global issues and work among non-Jewish people.

Tytuł:: Closed operators affiliated with a Banach algebra of operators
Autorzy:: Barnes, Bruce A.
Powiązania:: https://bibliotekanauki.pl/articles/1293309.pdf
Data publikacji:: 1992
Wydawca:: Polska Akademia Nauk. Instytut Matematyczny PAN
Tematy:: closed operator
spectrum
Fredholm operator
semigroup of operators
Banach algebra
Opis:: Let ℬ be a Banach algebra of bounded linear operators on a Banach space X. If S is a closed operator in X such that (λ - S)^{-1} ∈ ℬ for some number λ, then S is affiliated with ℬ. The object of this paper is to study the spectral theory and Fredholm theory relative to ℬ of an operator which is affiliated with ℬ. Also, applications are given to semigroups of operators which are contained in ℬ.
