We present here some fundamental but yet underlooked features of the propagation of weak ultrashort pulses (with D d s << 1, where D d is the Doppler width and s is the pulse duration) in resonant atomic media. We show that the pulse area behaviour and the pulse spectrum at resonance are governed by
A phase space cell method for prowdmg a global descrlptlon of the motions of a physical system IS outlined. The key feature IS a coarse-gram~ng approxlmotlon to the phase-space probablbty dlstrlbution. Constants of motion and other constramts are mcorporared to reduce the dlmenslonallty of computati
