Lorentzian SRT-transformation factors as solutions of oscillation-equations Holger Döring IQ-Berlin-Spandau Germany e-mail:haw-doering@t-online.deAbstract:Shown is the derivation of Lorentz-Einstein k-factor in SRT as an amplitude-term of oscillation-differential equations of second order.This case is shown for classical Lorentz-factor as solution of an equation for undamped oscillation as well as the developed theorem as a second solution for advanced SRT of fourth order with an equation for damped oscillation-states.This advanced term allows a calculation for any velocities by real rest mass.key-words: undamped oscillation; SRT; k-factor; Differential-equation of second order; Einstein-Lorentz; Amplitude-analogy; damped oscillation; developed SRT of fourth order
