A colimit decomposition for homotopy algebras in Cat
A colimit decomposition homotopy algebras Cat Category Theory
2012/6/25
Badzioch showed that in the category of simplicial sets each homotopy algebra of a Lawvere theory is weakly equivalent to a strict algebra. In seeking to extend this result to other contexts Rosicky o...
Brauer's generalized decomposition numbers and universal deformation rings
Universal deformation rings Brauer’s generalized decomposition numbers tame blocks dihedral defect groups semidihedral defect groups
2012/4/17
We study the problem of lifting to local rings certain mod 2 representations V of finite groups G which belong to 2-modular tame blocks B of G having at least two isomorphism classes of simple modules...
Decomposition of Polynomials
Decomposition of Polynomials Commutative Algebra Symbolic Computation
2011/8/25
Abstract: This diploma thesis is concerned with functional decomposition $f = g \circ h$ of polynomials. First an algorithm is described which computes decompositions in polynomial time. This algorith...
An improvement upon unmixed decomposition of an algebraic variety
unmixed decomposition weakly non-degenerate conditions
2011/1/18
Decomposing an algebraic variety into irreducible or equidimensional components is a fundamental task in classical algebraic geometry and has various applications in modern geometry engineering. Sever...
Decomposition of spinor groups by the involution σ' in exceptional Lie groups
Decomposition of spinor groups involution σ' in exceptional Lie groups

The compact exceptional Lie groups F4,E6,E7 and E8 have spinor groups as a subgroup as follows.
Modular absolute decomposition of equidimensional polynomial ideals
Modular absolute decomposition equidimensional polynomial ideals
2011/2/25
In this paper, we present a modular strategy which describes key properties of the absolute
primary decomposition of an equidimensional polynomial ideal defined by polynomials with rational coefficie...
Polar decomposition unquestionably provides a notion of factorization in the category of Hilbert spaces. But it does not fit existing categorical notions, mainly because its factors are not closed und...
Abelian JSJ decomposition of graphs of free abelian groups
Abelian JSJ decomposition graphs of free abelian groups
2011/1/19
A group G is a vGBS group if it admits a decomposition as a fi-nite graph of groups with all edge and vertex groups finitely generated and free abelian. We construct the JSJ decomposition of a vGBS gr...
The Generalized Schur Decomposition and the rank-$R$ set of real $I\times J\times 2$ arrays
The Generalized Schur Decomposition the rank-$R$ set
2010/11/22
It is known that a best low-rank approximation to multi-way arrays or higher-order tensors may not exist. This is due to the fact that the set of multi-way arrays with rank at most $R$ is not closed....
Higher-order derivatives of the QR and of the real symmetric eigenvalue decomposition in forward and reverse mode algorithmic differentiation
univariate Taylor polynomial arithmetic higher-order derivatives QR decomposition real symmetric eigenvalue decomposition
2010/12/15
We address the task of higher-order derivative evaluation of computer programs that contain QR
decompositions and real symmetric eigenvalue decompositions. The approach is a combination of univariate...
A Jordan decomposition for groups of finite Morley rank
Jordan decomposition groups of finite Morley rank
2010/12/8
We prove a Jordan decomposition theorem for minimal connected simple groups of finite Morley rank with non-trivial Weyl group. From this,we deduce a precise structural description of Borel subgroups o...

Identical Eigenmode Transmission System Channel Decomposition Perspective
2010/12/8
In the past few years considerable attention has been given to the design of Multiple-Input Multiple-Output (MIMO) Eigenmode Transmission Systems (EMTS). This paper presents an in-depth analysis of a ...

2010/1/22
We define the Littlewood-Paley decomposition associated with the Dunkl operators; from this decomposition we give the characterization of the Sobolev, H鰈der and Lebesgue spaces associated with the Dun...
摘要 By defining a concept of normal chains, an algorithm to decompose algebraicvarieties is presented, and the applications of this algorithm in solving polynomial equationsand primary decomposition of...
