Direct sum decompositions and indecomposable TQFTs [PDF]

Journal of Mathematical Physics, 1995
The decomposition of an arbitrary axiomatic topological quantum field theory or TQFT into indecomposable theories is given. In particular, unitary TQFTs in arbitrary dimensions are shown to decompose into a sum of theories in which the Hilbert space of the sphere is one-dimensional, and indecomposable two-dimensional theories are classified.

Systematics of U-spin sum rules for systems with direct sums

Journal of High Energy Physics
A rich mathematical structure underlying flavor sum rules has been discovered recently. In this work, we extend these findings to systems with a direct sum of representations. We prove several results for the general case.

Determination of N‑year Design Precipitation in the Czech Republic by Annual Maximum Series Method

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019
The sum of design precipitation of a selected repetition period, provided that it is evenly distributed over the river basin area, is a basic input for the calculation of the direct outflow volume by the curve number method.

Quasi-Projective Covers and Direct Sums [PDF]

Proceedings of the American Mathematical Society, 1970
In this paper R R denotes an associative ring with an identity, and all modules are unital left R R -modules. It is shown that the existence of a quasi-projective cover for each module implies that each module has a projective cover. By a similar technique the following statements are shown to be equivalent: 1.

Direct Sum Decomposition of the Integers [PDF]

Tokyo Journal of Mathematics, 1995
Denote by \(\mathbb{Z}(\mathbb{N})\) the set of all integers (all positive integers). If \(A,B\subseteq\mathbb{Z}\), then we put \(A+B= \{a+b: a\in A, b\in B\}\), \(A-B= \{a-b:a\in A, b\in B\}\). If \(A+B=\mathbb{Z}\) and every \(z\in\mathbb{Z}\) can be uniquely expressed in the form \(z=a+b\), then we write \(A\oplus B=\mathbb{Z}\) and \(\mathbb{Z ...

Exploring EADS Modules: Properties, Direct Sums, and Applications in Matrix Rings

Journal of Mathematics
We introduce the concept of an EADS module, defined such that for any decomposition M=A⊕B and any ec-complement C of A in M, the module satisfies M=A⊕C.

Higher-Order Extensions of C-Hyponormality via n-Quasi-C-Hyponormal Operators

Mathematics
In this paper, we investigate generalizations and extensions of C-hyponormal operators, focusing on the class of n-quasi-C-hyponormal operators. We provide a detailed structural analysis, including decomposition results that split an operator into a C ...

A Hyperstructural Approach to Semisimplicity

Axioms
In this paper, we provide the basic properties of (semi)simple hypermodules. We show that if a hypermodule M is simple, then (End(M),·) is a group, where End(M) is the set of all normal endomorphisms of M. We prove that every simple hypermodule is normal

A generalization of modules with the property (P*) [PDF]

Mathematica Moravica, 2017
I.A- Khazzi and P.F. Smith called a module M have the property (P*) if every submodule N of M there exists a direct summand K of M such that K ≤ N and N K C Rad(M K).
