A Simplified Model of Oscillating Universe: Alternative Deduction Of Friedmann Lematre Equations With A Negative Cosmological Constant


Among the various models of Universe commonly considered, the so called oscillatory class stands out. A Universe that oscillates following a simple harmonic motion evidently belongs to the above-mentioned class. The aim of this paper simply consists in deducing, in this specific case, the well known Friedmann-Lemaître relations without using Einstein field equations. Homogeneity and isotropy are obviously taken for granted.
