1. Decomposition: A decomposition is a representation of a given set as the union of a system of pairwise disjoint sets. In discrete geometry one frequently considers the decomposition of some space into closed domains which cover the entire space and whose ... (Mathematics) [100%] 2023-11-14
2. Decomposition: Decomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and ...

5. Langlands decomposition: In mathematics, the Langlands decomposition writes a parabolic subgroup P of a semisimple Lie group as a product \displaystyle{ P=MAN }[/math] of a reductive subgroup M, an abelian subgroup A, and a nilpotent subgroup N. A key application is ... [70%] 2024-01-08 [Lie groups] [Algebraic groups]...
6. Schur decomposition: In the mathematical discipline of linear algebra, the Schur decomposition or Schur triangulation, named after Issai Schur, is a matrix decomposition.

8. Primary decomposition: In mathematics, the Lasker–Noether theorem states that every Noetherian ring is a Lasker ring, which means that every ideal can be decomposed as an intersection, called primary decomposition, of finitely many primary ideals (which are related to, but not ...

10. Chemical decomposition: Chemical decomposition, or chemical breakdown, is the process or effect of simplifying a single chemical entity (normal molecule, reaction intermediate, etc.) into two or more fragments. Chemical decomposition is usually regarded and defined as the exact opposite of chemical synthesis. (Chemistry) [70%] 2023-11-30 [Inorganic chemistry] [Organic chemistry]...
11. Cartan decomposition: In mathematics, the Cartan decomposition is a decomposition of a semisimple Lie group or Lie algebra, which plays an important role in their structure theory and representation theory. It generalizes the polar decomposition or singular value decomposition of matrices. (Generalized matrix decomposition for Lie groups and Lie algebras) [70%] 2023-08-23 [Lie groups] [Lie algebras]...
12. Schmidt decomposition: In linear algebra, the Schmidt decomposition (named after its originator Erhard Schmidt) refers to a particular way of expressing a vector in the tensor product of two inner product spaces. It has numerous applications in quantum information theory, for example ... (Process in linear algebra) [70%] 2023-12-26 [Linear algebra] [Singular value decomposition]...
13. Jordan decomposition (of an endomorphism): The Jordan decomposition of an endomorphism $ g $ of a finite-dimensional vector space is the representation of $ g $ as the sum of a semi-simple and a nilpotent endomorphism that commute with each other: $ g = g _{s} + g _ ...

17. Ear decomposition: In graph theory, an ear of an undirected graph G is a path P where the two endpoints of the path may coincide, but where otherwise no repetition of edges or vertices is allowed, so every internal vertex of P ...
