On Lifting Idempotents

open access: yesCanadian Mathematical Bulletin, 1974
Let N be an ideal of a ring A. We say that idempotents modulo N can be lifted provided that for every a of A such that a2-a ∈ N there exists an element e2=e ∈ A such that e-a ∈ N. The technique of lifting idempotents is considered to be a fundamental tool in the classical theory of nonsemiprimitive Artinian rings (refer [2; p. 72]).

On idempotency of linear combinations of idempotent matrices

Applied Mathematics and Computation, 2004
Let \(P_1, P_2\) and \(P_3\) being any three different nonzero mutually commutative \(n\times n\) idempotent matrices, and \(c_1,c_2\) and \(c_3\) being nonzero scalars, the problem of characterizing some situations, where a linear combination of the form \(P=c_1P_1+c_2P_2\) or \(P=c_1P_1+c_2P_2+c_3P_3\), is also an idempotent matrix is considered ...

On the importance of idempotence

Proceedings of the thirty-eighth annual ACM symposium on Theory of Computing, 2006
Range searching is among the most fundamental problems in computational geometry. An n-element point set in Rd is given along with an assignment of weights to these points from some commutative semigroup. Subject to a fixed space of possible range shapes, the problem is to preprocess the points so that the total semigroup sum of the points lying within
