General mathematics

indefinite quadratic form

Mathematics; General mathematics

A quadratic form over an ordered field F , which represents both positive and negative elements. If every positive number in F is a square (for example, if F = R ), then an indefinite quadratic ...

hyperbolic transformation

Mathematics; General mathematics

A linear fractional function f(z)=\frac{az+b}{cz+d} where a, b, c, and d are complex constants with {ad-bc}\neq 0 has a pair of fixed points which are not necessarily distinct. This is so ...

independent linear equations

Mathematics; General mathematics

A system of linear equations in which deleting any equation would lead to the expansion of the solution set.

implicit enumeration method of integer programming

Mathematics; General mathematics

A method for solving zero-one linear programming problems by assigning selected values to some of the variables. If the solution of the resulting linear program is either infeasible or not optimal, ...

linear equations

Mathematics; General mathematics

A linear equation is any equation with two expressions set equal to each other. A linear equation is special because it has one or two variables and no variable is raised to a power greater than 1 or ...

localization

Mathematics; General mathematics

The process used to construct the field of fractions from an integral domain, i.e. a ring with no non-zero zero divisors. For example, the construction of the rational numbers (fractions) from ...
