  2. Determinant - Wikipedia

    en.wikipedia.org/wiki/Determinant

    These determinants are either 0 (by property 9) or else ±1 (by properties 1 and 12 below), so the linear combination gives the expression above in terms of the Levi-Civita symbol. While less technical in appearance, this characterization cannot entirely replace the Leibniz formula in defining the determinant, since without it the existence of ...

  3. Matrix determinant lemma - Wikipedia

    en.wikipedia.org/wiki/Matrix_determinant_lemma

    The determinant of the left hand side is the product of the determinants of the three matrices. Since the first and third matrix are triangular matrices with unit diagonal, their determinants are just 1. The determinant of the middle matrix is our desired value.

    In vector calculus, the Jacobian matrix (/ dʒ ə ˈ k oʊ b i ə n /, [1] [2] [3] / dʒ ɪ-, j ɪ-/) of a vector-valued function of several variables is the matrix of all its first-order partial derivatives.

  5. Fredholm determinant - Wikipedia

    en.wikipedia.org/wiki/Fredholm_determinant

    In mathematics, the Fredholm determinant is a complex-valued function which generalizes the determinant of a finite dimensional linear operator.It is defined for bounded operators on a Hilbert space which differ from the identity operator by a trace-class operator.

  6. Dieudonné determinant - Wikipedia

    Assume that K is finite over its center F.The reduced norm gives a homomorphism N n from GL n (K ) to F ×.We also have a homomorphism from GL n (K ) to F × obtained by composing the Dieudonné determinant from GL n (K ) to K × / [K ×, K ×] with the reduced norm N 1 from GL 1 (K ) = K × to F × via the abelianization.

  8. Cramer's rule - Wikipedia

    en.wikipedia.org/wiki/Cramer's_rule

    In the 2×2 case, if the coefficient determinant is zero, then the system is incompatible if the numerator determinants are nonzero, or indeterminate if the numerator determinants are zero. For 3×3 or higher systems, the only thing one can say when the coefficient determinant equals zero is that if any of the numerator determinants are nonzero ...

  9. Indefinite orthogonal group - Wikipedia

    en.wikipedia.org/wiki/Indefinite_orthogonal_group

    In mathematics, the indefinite orthogonal group, O(p, q) is the Lie group of all linear transformations of an n-dimensional real vector space that leave invariant a nondegenerate, symmetric bilinear form of signature (p, q), where n = p + q.
