  2. Hurwitz quaternion - Wikipedia

    en.wikipedia.org/wiki/Hurwitz_quaternion

    This factorization is not in general unique, even up to units and order, because a positive odd prime p can be written in 24(p+1) ways as a product of two irreducible Hurwitz quaternions of norm p, and for large p these cannot all be equivalent under left and right multiplication by units as there are only 24 units. However, if one excludes ...

  3. Routh–Hurwitz stability criterion - Wikipedia

    en.wikipedia.org/wiki/Routh–Hurwitz_stability...

    In the control system theory, the Routh–Hurwitz stability criterion is a mathematical test that is a necessary and sufficient condition for the stability of a linear time-invariant (LTI) dynamical system or control system. A stable system is one whose output signal is bounded; the position, velocity or energy do not increase to infinity as ...

  4. Routh–Hurwitz theorem - Wikipedia

    en.wikipedia.org/wiki/Routh–Hurwitz_theorem

    Let f(z) be a polynomial (with complex coefficients) of degree n with no roots on the imaginary axis (i.e. the line z = ic where i is the imaginary unit and c is a real number).Let us define real polynomials P 0 (y) and P 1 (y) by f(iy) = P 0 (y) + iP 1 (y), respectively the real and imaginary parts of f on the imaginary line.

  5. Stable polynomial - Wikipedia

    en.wikipedia.org/wiki/Stable_polynomial

    The Routh–Hurwitz theorem provides an algorithm for determining if a given polynomial is Hurwitz stable, which is implemented in the Routh–Hurwitz and Liénard–Chipart tests. To test if a given polynomial P (of degree d) is Schur stable, it suffices to apply this theorem to the transformed polynomial

  6. Hurwitz quaternion order - Wikipedia

    en.wikipedia.org/wiki/Hurwitz_quaternion_order

    The Hurwitz quaternion order is a specific order in a quaternion algebra over a suitable number field. The order is of particular importance in Riemann surface theory, in connection with surfaces with maximal symmetry , namely the Hurwitz surfaces . [ 1 ]

  7. Hurwitz polynomial - Wikipedia

    en.wikipedia.org/wiki/Hurwitz_polynomial

    In mathematics, a Hurwitz polynomial (named after German mathematician Adolf Hurwitz) is a polynomial whose roots (zeros) are located in the left half-plane of the complex plane or on the imaginary axis, that is, the real part of every root is zero or negative. [1] Such a polynomial must have coefficients that are positive real numbers.

  8. Hurwitz's automorphisms theorem - Wikipedia

    en.wikipedia.org/wiki/Hurwitz's_automorphisms...

    Many more finite simple groups are Hurwitz groups; for instance all but 64 of the alternating groups are Hurwitz groups, the largest non-Hurwitz example being of degree 167. The smallest alternating group that is a Hurwitz group is A 15. Most projective special linear groups of large rank are Hurwitz groups, (Lucchini, Tamburini & Wilson 2000 ...

  9. Hurwitz problem - Wikipedia

    en.wikipedia.org/wiki/Hurwitz_problem

    In mathematics, the Hurwitz problem (named after Adolf Hurwitz) is the problem of finding multiplicative relations between quadratic forms which generalise those known to exist between sums of squares in certain numbers of variables.
