On Amenability-Like Properties of a Class of Matrix Algebras

Journal of Mathematics, 2022
In this study, we show that a matrix algebra ℒℳIpA is a dual Banach algebra, where A is a dual Banach algebra and 1≤p≤2. We show that ℒℳIpℂ is Connes amenable if and only if I is finite, for every nonempty set I.

TRIANGULAR MATRIX REPRESENTATIONS OF SKEW MONOID RINGS [PDF]

, 2010
Let R be a ring and S a u.p.-monoid. Assume that there is a monoid homomorphism α : S → Aut (R). Suppose that α is weakly　rigid and lR(Ra) is pure as a left ideal of R for every element a ∈ R.

Representation of an MV-algebra by its triangular norms [PDF]

, 1998
Any given complete and atomic Boolean algebra can be embedded into a dense MV-algebra in such a way that the Boolean algebra formed by the idempotent elements of the MV-algebra is isomorphic to the given Boolean algebra.

Uniform bounds on the 1-norm of the inverse of lower triangular Toeplitz matrices [PDF]

, 2011
A uniform bound on the 1-norm is given for the inverse of a lower triangular Toeplitz matrix with non-negative monotonically decreasing entries whose limit is zero. The new bound is sharp under certain specified constraints.

Product of derivations on triangular banach algebras [PDF]

Journal of Hyperstructures, 2017
In this paper, we give a necessary and sufficient condition for the product of two derivations on the triangular Banach algebra to be a derivation. We also study the case where the product of derivations is commutative.

Triangular norm-based intuitionistic fuzzy BE-algebras and filters [PDF]

Notes on IFS
In this paper, intuitionistic fuzzy BE-algebra that a generalization of the BCK-algebra is introduced with respect to t-norms and t-conorms. The various algebraic properties of triangular norm-based intuitionistic fuzzy BE-algebras are studied in detail,
