Explicit formulas for exponential of 2×2 split-complex matrices
(Ankara University, 2022)Split-complex (hyperbolic) numbers are ordered pairs of real numbers, written in the form x + jy with j(2) - 1, used to describe the geometry of the Lorentzian plane. Since a null split-complex number does not have an ... -
