Życiński, Józef2025-11-252025-11-251978Analecta Cracoviensia, 1978, T. 10, s. 67-71.0209-0864https://theo-logos.pl/handle/123456789/39278Zawiera ilustrację.In the paper is considered the question under what conditions the entire spacetime could be determined by initial data specified on an achronal set S. Notions of Cauchy development, Cauchy surface and Cauchy horizon are introduced to show that some versions of principles of determinism could be discarded. Consequently, the principle of deterministic (interpretation, strongly supported by some Marxists, can be treated merely as a heuristic principle. The author wishes to express his gratitude to the Catholic University of America, Washington D. C., whose support made possible the preparation of this paper.plCC-BY-NC-ND - Uznanie autorstwa - Użycie niekomercyjne - Bez utworów zależnychhoryzont Cauchy’egokosmologiaastrofizykanauki przyrodniczekosmologia przyrodniczarozwinięcie Cauchy’egopowierzchnia Cauchy’egoCauchy horizoncosmologyastrophysicsnatural sciencesnatural cosmologyCauchy expansionCauchy surfaceArticle
