Abstract

Exact solutions of Einstein’s field equations corresponding to rotationally symmetric clusters of particles with zero net angular momentum are obtained The matter density ϱ is finite at the axis of symmetry and tends to zero asr→∞ and ϱ=0 corresponds to the flat metricПолучаются точные решения полевых уравнений Эйнштейна которые соответстуют ротационно симметричным кластерам частиц с нулевым суммарным моментом Плотность вещества ϱ является конечной на оси симметрии и стремится к нулю приr→∞ Случай ϱ=0 соответствует плоской метрикеSi ottengono soluzioni esatte delle equazioni di campo di Einstein corrispondenti ad ammassi di particelle a simmetria rotazionale con impulso angolare netto nullo La densitè di materia ϱ è finita sull’asse di simmetria e tende a zero perr→∞ inoltre ϱ=0 corrisponde a una metrica piana
