    Section 11(b) provides that 11. Any person charged with an offence has the right... (b) to be tried within a reasonable time; Section 11(b) can be taken to provide a right to a speedy trial. [3] The criteria by which the court will consider whether the rights of an accused under this provision have been infringed were set out in R. v. Askov (1990).

  4. Module (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Module_(mathematics)

    A module is called flat if taking the tensor product of it with any exact sequence of R-modules preserves exactness. Torsionless A module is called torsionless if it embeds into its algebraic dual. Simple A simple module S is a module that is not {0} and whose only submodules are {0} and S. Simple modules are sometimes called irreducible. [5 ...

    [11] At the end of the 19th century, the foundational crisis in mathematics and the resulting systematization of the axiomatic method led to an explosion of new areas of mathematics. [12] [6] The 2020 Mathematics Subject Classification contains no less than sixty-three first-level areas. [13]

    In numerical analysis and linear algebra, lower–upper (LU) decomposition or factorization factors a matrix as the product of a lower triangular matrix and an upper triangular matrix (see matrix multiplication and matrix decomposition).

  8. Explanation - Wikipedia

    en.wikipedia.org/wiki/Explanation

    The term explanation is sometimes used in the context of justification, e.g., the explanation as to why a belief is true. Justification may be understood as the explanation as to why a belief is a true one or an account of how one knows what one knows. It is important to be aware when an explanation is not a justification.

  9. Support of a module - Wikipedia

    en.wikipedia.org/wiki/Support_of_a_module

    The support of a finite module over a Noetherian ring is always closed under specialization. [ citation needed ] Now, if we take two polynomials f 1 , f 2 ∈ R {\displaystyle f_{1},f_{2}\in R} in an integral domain which form a complete intersection ideal ( f 1 , f 2 ) {\displaystyle (f_{1},f_{2})} , the tensor property shows us that
