طوبولوجيا الزمكان (بالإنجليزية: Spacetime topology) هي البنية الطوبولوجية للزمكان، وهو موضوع تمت دراسته بشكل أساسي في النسبية العامة. نماذج هذه النظرية الفيزيائية الجاذبية على أنها انحناء مشعب لورنتزيان رباعي الأبعاد (الزمكان) وبالتالي تصبح مفاهيم الطوبولوجيا مهمة في تحليل الجوانب المحلية والعالمية للزمكان. تعتبر دراسة طوبولوجيا الزمكان مهمة بشكل خاص في علم الكون الفيزيائي. (ar) Spacetime topology is the topological structure of spacetime, a topic studied primarily in general relativity. This physical theory models gravitation as the curvature of a four dimensional Lorentzian manifold (a spacetime) and the concepts of topology thus become important in analysing local as well as global aspects of spacetime. The study of spacetime topology is especially important in physical cosmology. (en) La topologia dello spazio-tempo o topologia spazio-temporale, la struttura topologica dello spazio-tempo, è un argomento studiato principalmente nella relatività generale. Questa teoria fisica modella la gravitazione utilizzando una varietà lorentziana (uno spazio-tempo) e i concetti di topologia diventano perciò importanti nell'analisi degli aspetti sia locali che globali dello spazio-tempo. Lo studio della topologia dello spazio-tempo è importante specialmente in cosmologia fisica. (it) Topologia do espaço-tempo é a estrutura topológica do espaço-tempo, um tópico estudado principalmente na relatividade geral. Este modelos da teoria física da gravitação como uma variedade de Lorentz (um espaço-tempo) e os conceitos de topologia, assim, tornam-se importantes na análise local, bem como aspectos globais do espaço-tempo. O estudo da topologia do espaço-tempo é especialmente importante em cosmologia física. (pt) |
