Phys. Rev. D 41, 2444–2448 (1990)Proof of the closed-universe recollapse conjecture for general bianchi type-IX cosmologiesReceived 13 November 1989; published in the issue dated 15 April 1990 It is proven that there do not exist any Bianchi type-IX universes which expand for an infinite time, provided only that the matter satisfies the dominant energy condition and has non-negative average pressure (i.e., a non-negative trace of the spatial projection of the stress-energy tensor). This generalizes a proof recently given by us for the case of diagonal Bianchi type-IX solutions. © 1990 The American Physical Society URL:
