  2. Bivector - Wikipedia

    en.wikipedia.org/wiki/Bivector

    More precisely, a bivector that can be expressed as an exterior product is called simple; in up to three dimensions all bivectors are simple, but in higher dimensions this is not the case. [4] The exterior product of two vectors is alternating, so a ∧ a is the zero bivector, and b ∧ a is the negative of the bivector a ∧ b, producing the ...

  3. Bivector (complex) - Wikipedia

    en.wikipedia.org/wiki/Bivector_(complex)

    The first term was named with quaternions, and the second about a decade later, as in Lectures on Quaternions (1853). [1]: 665 The popular text Vector Analysis (1901) used the term. [4]: 249 Given a bivector r = r 1 + hr 2, the ellipse for which r 1 and r 2 are a pair of conjugate semi-diameters is called the directional ellipse of the bivector r.

  4. Sylvester's triangle problem - Wikipedia

    en.wikipedia.org/wiki/Sylvester's_triangle_problem

    sum of three equal lengthed vectors. Sylvester's theorem or Sylvester's formula describes a particular interpretation of the sum of three pairwise distinct vectors of equal length in the context of triangle geometry. It is also referred to as Sylvester's (triangle) problem in literature, when it is given as a problem rather than a theorem.

  5. Analytic geometry - Wikipedia

    en.wikipedia.org/wiki/Analytic_geometry

    In mathematics, analytic geometry, also known as coordinate geometry or Cartesian geometry, is the study of geometry using a coordinate system. This contrasts with synthetic geometry . Analytic geometry is used in physics and engineering , and also in aviation , rocketry , space science , and spaceflight .

  6. Universal geometric algebra - Wikipedia

    en.wikipedia.org/wiki/Universal_geometric_algebra

    Some r-vectors are scalars (r = 0), vectors (r = 1) and bivectors (r = 2). One may generate a finite-dimensional GA by choosing a unit pseudoscalar (I). The set of all vectors that satisfy = is a vector space. The geometric product of the vectors in this vector space then defines the GA, of which I is a member.

  7. Covariance and contravariance of vectors - Wikipedia

    en.wikipedia.org/wiki/Covariance_and_contra...

    Secondly, in the classical approach to differential geometry, it is not bases of the tangent bundle that are the most primitive object, but rather changes in the coordinate system. Vectors with contravariant components transform in the same way as changes in the coordinates (because these actually change oppositely to the induced change of basis).

  8. Metric signature - Wikipedia

    en.wikipedia.org/wiki/Metric_signature

    The signature of a metric tensor is defined as the signature of the corresponding quadratic form. [2] It is the number (v, p, r) of positive, negative and zero eigenvalues of any matrix (i.e. in any basis for the underlying vector space) representing the form, counted with their algebraic multiplicities.

  9. Beltrami–Klein model - Wikipedia

    Many hyperbolic lines through point P not intersecting line a in the Beltrami Klein model A hyperbolic triheptagonal tiling in a Beltrami–Klein model projection. In geometry, the Beltrami–Klein model, also called the projective model, Klein disk model, and the Cayley–Klein model, is a model of hyperbolic geometry in which points are represented by the points in the interior of the unit ...
