Matrix decompositions | Numerical linear algebra | Operator theory
In linear algebra, the Cholesky decomposition or Cholesky factorization (pronounced /ʃəˈlɛski/ shə-LES-kee) is a decomposition of a Hermitian, positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose, which is useful for efficient numerical solutions, e.g., Monte Carlo simulations. It was discovered by André-Louis Cholesky for real matrices, and posthumously published in 1924.When it is applicable, the Cholesky decomposition is roughly twice as efficient as the LU decomposition for solving systems of linear equations. (Wikipedia).

What are Graph Decompositions? | Graph Decomposition, Graph Theory
What is a graph decomposition? Graph decompositions are studied quite extensively by many in graph theory, and we’ll go over what they are, and plenty of examples in today’s video graph theory lesson! We can decompose a graph into subgraphs, but in order for this to be a decomposition the
