New characterizations of EP, generalized normal and generalized Hermitian elements in rings
We present a number of new characterizations of EP elements in rings with involution in purely algebraic terms. Then, we study equivalent conditions for an element a in a ring with involution to satisfy ana∗ = a∗an or a = (a∗)n for arbitrary n ∈ N . For n = 1, we present some new characterizations of normal and Hermitian elements in rings with involution.
متن کاملAlmost power-Hermitian rings
In this paper we define a new type of rings ”almost powerhermitian rings” (a generalization of almost hermitian rings) and establish several sufficient conditions over a ring R such that, every regular matrix admits a diagonal power-reduction.
متن کاملInvertible Rings and Axiomatic Algebra
Assume λ ≥ 0. Every student is aware that Ω > 0. We show that ε(Yβ,ψ) ∈ YC ,l. Thus the work in [14] did not consider the Smale case. Thus this could shed important light on a conjecture of Poisson.
متن کاملShort, Invertible Elements in Partially Splitting Cyclotomic Rings and Applications to Lattice-Based Zero-Knowledge Proofs
When constructing practical zero-knowledge proofs based on the hardness of the RingLWE or the Ring-SIS problems over polynomial rings Zp[X]/(X + 1), it is often necessary that the challenges come from a set C that satisfies three properties: the set should be large (around 2), the elements in it should have small norms, and all the non-zero elements in the difference set C −C should be invertib...
متن کاملSome properties of Invertible Elements in Fuzzy Banach algebras
In this paper, we introduce fuzzy Banach algebra and study the properties of invertible elements and its relation with opensets. We obtain some interesting results.
