Correct definition of infinite values of variables and derivatives made by enclosure into compact. Transformation is fulfilled automatically by Maple12 package. The offered method used in numerical integration of the equations of Einstein with extremely wide range of values of variables and in unlimited area.phase portraitqualitative analysiscompactificationprojectiveфазовый портреткачественный анализкомпактификацияпроективный
