Primary decomposition over rings graded by finitely generated Abelian groups

open access: yesJournal of Algebra, 2007
Let A be a Noetherian ring which is graded by a finitely generated Abelian group G. In general, for G-graded modules there do not exist primary decompositions which are graded themselves.

Algorithms for computing a primary ideal decomposition without producing intermediate redundant components

open access: yesJournal of Symbolic Computation, 2011
In Noro (2010) we proposed an algorithm for computing a primary ideal decomposition by using the notion of a separating ideal and showed that it can efficiently decompose several examples which are hard to decompose using existing algorithms.

Movement Decomposition in the Primary Motor Cortex

open access: yesCerebral Cortex, 2018
A complex action can be described as the composition of a set of elementary movements. While both kinematic and dynamic elements have been proposed to compose complex actions, the structure of movement decomposition and its neural representation remain ...

Local dual spaces and primary decomposition

open access: yesJournal of Symbolic Computation
Generalizing the concept of the Macaulay inverse system, we introduce a way to describe localizations of an ideal in a polynomial ring. This leads to an approach to the differential primary decomposition as a description of the affine scheme defined by ...

Primary decompositions in lattices

Algebra Universalis, 1994
A general definition of primary theory for semilattices is given which generalizes all known decompositions in noncommutative rings and multiplicative lattices. It is proved that there exist minimal primary decompositions. The author gives a new notion of radicals for semilattices, which have properties similar to the nilpotent radicals of commutative ...
