Magma Computer Algebra System - Mathematical Areas Covered By The System

Mathematical Areas Covered By The System

  • Group theory
Magma includes permutation, matrix, finitely-presented, soluble, abelian (finite or infinite), polycyclic, braid and straight-line program groups. Several databases of groups are also included.
  • Number theory
Magma contains asymptotically-fast algorithms for all fundamental integer and polynomial operations, such as the Schönhage–Strassen algorithm for fast multiplication of integers and polynomials. Integer factorization algorithms include the Elliptic Curve Method, the Quadratic sieve and the Number field sieve.
  • Algebraic number theory
Magma includes the KANT computer algebra system for comprehensive computations in algebraic number fields. A special type also allows one to compute in the algebraic closure of a field.
  • Module theory and linear algebra
Magma contains asymptotically-fast algorithms for all fundamental dense matrix operations, such as Strassen multiplication.
  • Sparse matrices
Magma contains the structured Gaussian elimination and Lanczos algorithms for reducing sparse systems which arise in index calculus methods, while Magma uses Markowitz pivoting for several other sparse linear algebra problems.
  • Lattices and the LLL algorithm
Magma has a provable implementation of fpLLL, which is an LLL algorithm for integer matrices which uses floating point numbers for the Gram–Schmidt coefficients, but such that the result is rigorously proven to be LLL-reduced.
  • Commutative algebra and Gröbner bases
Magma has an efficient implementation of the Faugère F4 algorithm for computing Gröbner bases.
  • Representation theory
Magma has extensive tools for computing in representation theory, including the computation of character tables of finite groups and the Meataxe algorithm.
  • Invariant theory
Magma has a type for invariant rings of finite groups, for which one can primary, secondary and fundamental invariants, and compute with the module structure.
  • Lie theory
  • Algebraic geometry
  • Arithmetic geometry
  • Finite incidence structures
  • Cryptography
  • Coding theory
  • Optimization

Famous quotes containing the words mathematical, areas, covered and/or system:

    “It is by a mathematical point only that we are wise, as the sailor or the fugitive slave keeps the polestar in his eye; but that is sufficient guidance for all our life. We may not arrive at our port within a calculable period, but we would preserve the true course.”
    —Henry David Thoreau (1817–1862)

    “The planet on which we live is poorly organized, many areas are overpopulated, others are reserved for a few, technology’s potential is only in part realized, and most people are starving.”
    —Friedrich Dürrenmatt (1921–1990)

    “My safe, safe psychosis is broken.
    It was hard.
    It was made of stone.
    It covered my face like a mask.
    But it has cracked.”
    —Anne Sexton (1928–1974)

    “An avant-garde man is like an enemy inside a city he is bent on destroying, against which he rebels; for like any system of government, an established form of expression is also a form of oppression. The avant-garde man is the opponent of an existing system.”
    —Eugène Ionesco (b. 1912)
