Prokhorov's theorem. In measure theory Prokhorov's theorem relates tightness of measures to relative compactness (and hence weak convergence) in the space of probability measures. It is credited to the Soviet mathematician Yuri Vasilyevich Prokhorov, who considered probability measures on complete separable metric spaces. The term "Prokhorov ...
Yuri Vasilyevich Prokhorov (Russian: Ю́рий Васи́льевич Про́хоров; 15 December 1929 – 16 July 2013) was a Soviet and Russian mathematician, active in the field of probability theory. He was a PhD student of Andrey Kolmogorov at the Moscow State University, where he obtained his PhD in 1956.
Lévy–Prokhorov metric. In mathematics, the Lévy–Prokhorov metric (sometimes known just as the Prokhorov metric) is a metric (i.e., a definition of distance) on the collection of probability measures on a given metric space. It is named after the French mathematician Paul Lévy and the Soviet mathematician Yuri Vasilyevich Prokhorov ...
Conformal cyclic cosmology (CCC) is a cosmological model in the framework of general relativity and proposed by theoretical physicist Roger Penrose. [1] [2] [3] In CCC, the universe iterates through infinite cycles, with the future timelike infinity (i.e. the latest end of any possible timescale evaluated for any point in space) of each previous iteration being identified with the Big Bang ...
Prokhorov wrote in his blog that "if this is his personal conscious position, then he has no place in the party." In August 2011, political analyst Alexei Makarkin expressed the opinion that the Right Cause election campaign would be very problematic, since Prokhorov lacked both political and party-building experience.
Proof theory is a major branch [1] of mathematical logic and theoretical computer science within which proofs are treated as formal mathematical objects, facilitating their analysis by mathematical techniques. Proofs are typically presented as inductively-defined data structures such as lists, boxed lists, or trees, which are constructed ...
The ekpyrotic universe (/ ˌ ɛ k p aɪ ˈ r ɒ t ɪ k /) [1] is a cosmological model of the early universe that explains the origin of the large-scale structure of the cosmos.The model has also been incorporated in the cyclic universe theory (or ekpyrotic cyclic universe theory), which proposes a complete cosmological history, both the past and future.
Anatoliy Volodymyrovych Skorokhod ( Ukrainian: Анато́лій Володи́мирович Скорохо́д; September 10, 1930 – January 3, 2011) [ 1] was a Soviet and Ukrainian mathematician. Skorokhod is well-known for a comprehensive treatise on the theory of stochastic processes, co-authored with Gikhman. [ 2][ 3][ 4]
