CASA is a special-purpose system for computational algebra and constructive algebraic geometry. The system has been developed since The system is built on the kernel of the widely used computer algebra system Maple. It is able to perform simple and sophisticated operations on multivaraiate polynomial s and on various data related to them ideals, modules, matrices, rational functions.

For example, it can readily compute Grobner bases, syzygies and minimal free resolution, intersection, division, the radical of an ideal, the ideal of zero-dimensional schemes, Poincare' series and Hilbert functions, factorization of polynomial s, toric ideals. The capabilities of CoCoA and the flexibility of its use are further enhanced by the dedicated high-level programming language.

For convenience, the system offers a textual interface, an Emacs mode, and a graphical user interface common to most platforms. Fermat is a super calculator - computer algebra system, in which the basic items being computed can be rational numbers, modular numbers, elements of finite fields, multivariable polynomial s, multivariable rational functions, or multivariable polynomial s modulo other polynomial s.

It is shareware. Further, polynomial s p, q,.. It is possible to allow Laurent polynomial s. Once the computational ring is established in this way, all computations are of elements of this ring. GAP is a system for computational discrete algebra, with particular emphasis on Computational Group Theory. GAP provides a programming language, a library of thousands of functions implementing algebraic algorithms written in the GAP language as well as large data libraries of algebraic objects.

GAP is used in research and teaching for studying groups and their representations, rings, vector spaces, algebras, combinatorial structures, and more. GAP is developed by international cooperation.

You can study and easily modify or extend GAP for your special use. It contains different program modules and is fully compatible with the LinBox linear algebra library and the Athapascan environment, which permits parallel programming. It has been developed under the project leadership of Prof. LiE is the name of a software package that enables mathematicians and physicists to perform computations of a Lie group theoretic nature. It focuses on the representation theory of complex semisimple reductive Lie groups and algebras, and on the structure of their Weyl groups and root systems.

LiE does not compute directly with elements of the Lie groups and algebras themselves; it rather computes with weights, roots, characters and similar objects. LinBox has the following top-level functions: solve linear system, matrix rank, determinant, minimal polynomial , characteristic polynomial , Smith normal form and trace. A good collection of finite field and ring implementations is provided, for use with numerous black box matrix storage schemes. Magma is a large, well-supported software package designed to solve computationally hard problems in algebra, number theory, geometry and combinatorics.

It provides a mathematically rigorous environment for computing with algebraic, number-theoretic, combinatoric and geometric objects. Maple is an environment for scientific and engineering problem-solving, mathematical exploration, data visualization and technical authoring. Mathematica seamlessly integrates a numeric and symbolic computational engine, graphics system, programming language, documentation system, and advanced connectivity to other applications. Mathomatic is a free, portable, general-purpose CAS Computer Algebra System and calculator software that can symbolically solve, simplify, combine, and compare equations, perform complex number and polynomial arithmetic , etc.

It does some calculus and is very easy to use. MuPAD is a mathematical expert system for doing symbolic and exact algebraic computations as well as numerical calculations with almost arbitrary accuracy. For example, the number of significant digits can be chosen freely. Apart from a vast variety of mathematical libraries the system provides tools for high quality visualization of 2- and 3-dimensional objects. On Microsoft Windows, Apple Macintosh and Linux systems, MuPAD offers a flexible notebook concept for creating mathematical documents combining texts, graphics, formulas, computations and mathematical visualizations and animations.

Thus it offers a natural integration in Office applications like Word or PowerPoint as well as others. Normaliz is a tool for computations in affine monoids, vector configurations, lattice polytopes, and rational cones. Its input data can be specified in terms of a system of generators or vertices or a system of linear homogeneous Diophantine equations, inequalities and congruences or a binomial ideal. Normaliz computes the dual cone of a rational cone in other words, given generators, Normaliz computes the defining hyperplanes, and vice versa , a placing or lexicographic triangulation of a vector configuration resulting in a triangulation of the cone generated by it , the Hilbert basis of a rational cone, the lattice points of a lattice polytope, the normalization of an affine monoid, the Hilbert or Ehrhart series and the Hilbert or Ehrhart quasi polynomial under a Z-grading for example, for rational polytopes , NEW: generalized or weighted Ehrhart series and Lebesgue integrals of polynomial s over rational polytopes via NmzIntegrate, a description of the cone and lattice under consideration by a system of inequalities, equations and congruences.

It will be useful to have some familiarity with programming. Topics: Basic type theory: terms and types, function types, dependent types, inductive types. Most of the material will be developed using the dependently typed language Idris. Connections with programming in functional languages will be explored. Manin, Yu. Srivastava, S.
