Existence of a measurable modification of a stochastic process continuous in probability is an immediate consequence. 2027 BA WOS 10000 10100 10103 2 RVO:67985556 https://hdl.handle.net/11104/0374440 S A COMPUTERSCIENCE.CYBERNETICS 1.1 0.1 14.7 0.00058 0.288 978 43 0.378 34 2.47 255 Q3 2.000 43 Q3 42.2 0.27 Q3 42.2 2026 SCOPUS PUBMED WOS cav_un_epca*0297163 Kybernetika Roč. 62 č. 1 2026 7 17 0023-5954 Ústav teorie informace a automatizace AV ČR, v. v. i.
