De- Moivre’s and Euler Formulas for Matrices of Split Quaternions
In this paper, real matrix representations of split quaternions are examined in terms of the casual character of quaternion. Then, we give De-Moivre’ s formula for real matrices of timelike and spacelike split quaternions, separately. Finally, we state the Euler theorem for real matrices of pure split quaternions.
متن کاملSome Linear and Some Quadratic Recursion Formulas
§ 1. Introduction We shall mainly deal with linear recursion formulas of the type n-1 (l. 1) f(1) = 1 ; /(n) _ i~ ck f(n-k) (n = 2, 3,. . .), k=1 and with quadratic formulas of the type n-1 (1. 2) f(1) = 1 ; /(n) _ d, f(k)/(n-k) (n = 2,3. . .). k=1 We assume that ck > 0, d k > 0 (k = 1, 2,. . .). In a previous paper [1] we discussed (1. 1) under the condition X° ck = 1, and further special assu...
متن کاملOn Kronecker limit formulas for real quadratic fields
Let ζ(s,C) be the partial zeta function attached to a ray class C of a real quadratic field. We study this zeta function at s = 1 and s = 0, combining some ideas and methods due to Zagier and Shintani. The main results are (1) a generalization of Zagier’s formula for the constant term of the Laurent expansion at s = 1, (2) some expressions for the value and the first derivative at s = 0, relate...
متن کاملSome explicit formulas of Lyapunov exponents for 3D quadratic mappings
This paper shows that there exist six different cases where it is possible to find rigorously a Lyapunov exponent for 3-D quadratic mappings. An elementary example is also given and discussed.
متن کاملExplicit formulas for units in certain quadratic number fields
There is a class of quadratic number fields for which it is possible to find an explicit continued fraction expansion of a generator and hence an explicit formula for the fundamental unit. One therewith displays a family of quadratic fields with relatively large regulator. The formula for the fundamental unit seems far simpler than the continued fraction expansion, yet the expansion seems neces...
