Idempotents and structures of rings [PDF]
, 2016 Recall that an n-by-n generalized matrix ring is defined in terms of sets of rings (Formula presented.)-bimodules (Formula presented.) and bimodule homomorphisms (Formula presented.), where the set of diagonal matrix units (Formula presented.) form a ...

Vector valued logarithmic residues and the extraction of elementary factors [PDF]
An analysis is presented of the circumstances under which, by the extraction of elementary factors, an analytic Banach algebra valued function can be transformed into one taking invertible values only. Elementary factors are generalizations of the simple

On inverse categories with split idempotents [PDF]
, 2015 summary:We present some special properties of inverse categories with split idempotents. First, we examine a Clifford-Leech type theorem relative to such inverse categories.

Algebras generated by two idempotents [PDF]
, 1981 It is shown that a noncommutative simple algebra generated over a field F by two idempotents is necessarily the ring of 2×2 matrices over a simple extension of F, and that every matrix ring over a field K can be generated over K by three ...

, 2012 An idempotent satisfies the equation x2 = x. In ordinary arithmetic, this is so easy to solve it’s boring. We delight the mathematical palette here, topping idempotents off with modular arithmetic and a series of exercises determining for which n there ...

Lifting Idempotents in Associative Pairs [PDF]
, 1999 In 1977, Nicholson developed the theory of suitable rings (Trans. Amer. Math. Soc.229 (1977), 269–278), namely, those in which idempotents lift modulo every left (right) ideal.

, 2012 Cyclic codes give us the most probable method by which we may detect and correct data transmission errors. These codes depend on the development of advanced mathematical concepts.

Lifting to non-integral idempotents [PDF]
, 2001 In the first section of this paper, we illustrate (for a finite group G and the field of fractions K of a suitable complete dvr R) how to produce all central idempotents of Z(KG) from knowledge of the images of Z(RG) modulo certain powers of J(R). In the

Idempotents in intensional type theory
, 2017 We study idempotents in intensional Martin-L\"of type theory, and in particular the question of when and whether they split. We show that in the presence of propositional truncation and Voevodsky's univalence axiom, there exist idempotents that do not ...

Unbounded nilpotents and idempotents [PDF]
, 1988 This paper is concerned with unbounded operators in Hilbert space with domain containing their range and, in particular, investigates unbounded nilpotents and ...
