  2. Linear fractional transformation - Wikipedia

    en.wikipedia.org/wiki/Linear_fractional...

    Here, the 3 × 3 matrix components refer to the incoming, bound and outgoing states. Perhaps the simplest example application of linear fractional transformations occurs in the analysis of the damped harmonic oscillator. Another elementary application is obtaining the Frobenius normal form, i.e. the companion matrix of a polynomial.

  3. Mapy.cz - Wikipedia

    en.wikipedia.org/wiki/Mapy.cz

    Mapy.cz is a map portal [3] and mobile app [4] that covers the entire world. It is available in multiple languages. The map of the Czech Republic is based on proprietary map data, while maps for the rest of the world are created using data from OpenStreetMap and many other sources. The app's features include a route planner for driving, cycling ...

  5. Irreducible fraction - Wikipedia

    en.wikipedia.org/wiki/Irreducible_fraction

    An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) is a fraction in which the numerator and denominator are integers that have no other common divisors than 1 (and −1, when negative numbers are considered). [1]

  6. Alternating multilinear map - Wikipedia

    en.wikipedia.org/wiki/Alternating_multilinear_map

    In mathematics, more specifically in multilinear algebra, an alternating multilinear map is a multilinear map with all arguments belonging to the same vector space (for example, a bilinear form or a multilinear form) that is zero whenever any pair of its arguments is equal.

  7. Contraction mapping - Wikipedia

    en.wikipedia.org/wiki/Contraction_mapping

    Contractive maps are sometimes called Lipschitzian maps. If the above condition is instead satisfied for k ≤ 1, then the mapping is said to be a non-expansive map . More generally, the idea of a contractive mapping can be defined for maps between metric spaces.

  8. Möbius transformation - Wikipedia

    en.wikipedia.org/wiki/Möbius_transformation

    Firstly, the projective linear group PGL(2, K) is sharply 3-transitive – for any two ordered triples of distinct points, there is a unique map that takes one triple to the other, just as for Möbius transforms, and by the same algebraic proof (essentially dimension counting, as the group is 3-dimensional). Thus any map that fixes at least 3 ...

  9. Diophantine approximation - Wikipedia

    en.wikipedia.org/wiki/Diophantine_approximation

    So equivalence is defined by an integer Möbius transformation on the real numbers, or by a member of the Modular group (), the set of invertible 2 × 2 matrices over the integers. Each rational number is equivalent to 0; thus the rational numbers are an equivalence class for this relation.
