Question: Which mathematician worked with algebraic geometry instead of probability theory, Askold Khovanskii or Andrey Kolmogorov?

In probability theory, Kolmogorov's Three-Series Theorem, named after Andrey Kolmogorov, gives a criterion for the almost sure convergence of an infinite series of random variables in terms of the convergence of three different series involving properties of their probability distributions. Kolmogorov's three-series theorem, combined with Kronecker's lemma, can be used to give a relatively easy proof of the Strong Law of Large Numbers. <P2-S0> Derived algebraic geometry (also called spectral algebraic geometry) is a branch of mathematics that generalizes algebraic geometry to a situation where commutative rings, which provide a local chart, are replaced by ring spectra in algebraic topology, whose higher homotopy accounts for the non-discreteness (e.g., Tor) of the structure sheaf. <P2-S1>  Grothendieck's scheme theory allows the structure sheaf to carry nilpotent elements. Derived algebraic geometry can be thought of as an extension of this, and provides natural settings for intersection theory (or motivic homotopy theory) of singular algebraic varieties and cotangent complexes in deformation theory (cf. F. Francis). In mathematics, specifically in the theory of Markovian stochastic processes in probability theory, the Chapman–Kolmogorov equation is an identity relating the joint probability distributions of different sets of coordinates on a stochastic process.  The equation was derived independently by both the British mathematician Sydney Chapman and the Russian mathematician Andrey Kolmogorov. <P3-S0> Andrei Yuryevich Okounkov (Russian: Андре́й Ю́рьевич Окунько́в , "Andrej Okun'kov") (born July 26, 1969) is a Russian mathematician who works on representation theory and its applications to algebraic geometry, mathematical physics, probability theory and special functions. <P3-S1>  He is currently a professor at Columbia University and the academic supervisor of HSE International Laboratory of Representation Theory and Mathematical Physics. <P3-S2>  In 2006, he received the Fields Medal "for his contributions to bridging probability, representation theory and algebraic geometry." In probability theory, Kolmogorov's inequality is a so-called "maximal inequality" that gives a bound on the probability that the partial sums of a finite collection of independent random variables exceed some specified bound.  The inequality is named after the Russian mathematician Andrey Kolmogorov. Andrey Nikolaevich Kolmogorov (Russian: Андрей Николаевич Колмогоров ; ] , 25 April 1903 – 20 October 1987) was a 20th-century Soviet mathematician who made significant contributions to the mathematics of probability theory, topology, intuitionistic logic, turbulence, classical mechanics, algorithmic information theory and computational complexity. In Kolmogorov's probability theory, the probability "P" of some event "E", denoted formula_1, is usually defined such that "P" satisfies the Kolmogorov axioms, named after the Russian mathematician Andrey Kolmogorov, which are described below. In probability theory, the Borel–Kolmogorov paradox (sometimes known as Borel's paradox) is a paradox relating to conditional probability with respect to an event of probability zero (also known as a null set).  It is named after Émile Borel and Andrey Kolmogorov. Askold Georgievich Khovanskii (Russian: Аскольд Георгиевич Хованский ; born 3 June 1947, Moscow) is a Russian and Canadian mathematician currently a professor of mathematics at the University of Toronto, Canada.  His areas of research are algebraic geometry, commutative algebra, singularity theory, differential geometry and differential equations. His research is in the development of the theory of toric varieties and Newton polyhedra in algebraic geometry.  He is also the inventor of the theory of fewnomials. In probability theory, Kolmogorov's criterion, named after Andrey Kolmogorov, is a theorem giving a necessary and sufficient condition for a Markov chain or continuous-time Markov chain to be stochastically identical to its time-reversed version.
