In mathematics, the Lyusternik–Schnirelmann category (or, Lusternik–Schnirelmann category, LS-category) of a topological space formula_1 is the homotopical invariant defined to be the smallest integer number formula_2 such that there is an open covering formula_3 of formula_1 with the property that each inclusion map formula_5 is nullhomotopic.
 For example, if formula_1 is a sphere, this takes the value two.
Dmitri Victorovich Anosov (Russian: Дми́трий Ви́кторович Ано́сов ; November 30, 1936 – August 5, 2014) was a Soviet and Russian mathematician, known for his contributions to dynamical systems theory.
The MIXMAX generator is a family of pseudorandom number generators (PRNG) and is based on Anosov C-systems (Anosov diffeomorphism) and Kolmogorov K-systems (Kolmogorov automorphism).
 It was introduced in a 1986 preprint by G. Savvidy and N. Ter-Arutyunyan-Savvidy and published in 1991.
Nikolai Pavlovich Anosov (Russian: Никола́й Па́влович Ано́сов ; 17 February [O.S. 5 February] 1900 – 2 December 1962) was a Soviet conductor and pedagogue who conducted the Moscow State Symphony Orchestra (МГАСО) after Lev Steinberg.
 He is father of Gennady Rozhdestvensky, who adopted the maiden name of his mother, soprano Natalya Rozhdestvenskaya in its masculine form to avoid the appearance of nepotism when making his own career, and the painter P. N. Anosov.
Victor Alexandrovich Schnirelmann (Russian: Виктор Александрович Шнирельман , b. 18 May 1949, Moscow; frequently spelled Shnirelman in his English-language publications) is a Russian historian, ethnologist and a member of Academia Europaea (since 1998).
 He is a senior researcher of N. N. Miklukho-Maklai Institute of Ethnology and Anthropology at the Russian Academy of Sciences and an author of over 300 works, including over 20 monographies on archaeology.
 Schnirelmann's main fields include the ideologies of nationalism in Russia and CIS, ethnocentrism and irredentism.
Lev Genrikhovich Schnirelmann (also Shnirelman, Shnirel'man; "Лев Ге́нрихович Шнирельма́н" ; January 2, 1905 – September 24, 1938) was a Soviet mathematician who worked on number theory, topology and differential geometry.
Systolic category is a numerical invariant of a closed manifold "M", introduced by Mikhail Katz and Yuli Rudyak in 2006, by analogy with the Lusternik–Schnirelmann category.
 The invariant is defined in terms of the systoles of "M" and its covers, as the largest number of systoles in a product yielding a curvature-free lower bound for the total volume of "M".
 The invariant is intimately related to the Lusternik-Schnirelmann category.
 Thus, in dimensions 2 and 3, the two invariants coincide.
 In dimension 4, the systolic category is known to be a lower bound for the Lusternik–Schnirelmann category.
In mathematics, more particularly in the fields of dynamical systems and geometric topology, an Anosov map on a manifold "M" is a certain type of mapping, from "M" to itself, with rather clearly marked local directions of "expansion" and "contraction".
 Anosov systems are a special case of Axiom A systems.
The "Statue of Metallurgist Anosov" in Zlatoust city is situated on the main square of the historical center of Zlatoust, Chelyabinsk Oblast in Russia.The statue was erected in honor of Russian General-Major, metallurgist and governor of the Ural District, Anosov Pavel Petrovich, and unveiled on 19 December 1954.
 It was created by Moscow sculptors A.P. Antropov, N.L. Shtamm, and architect T.L. Shulgina.
The inscribed square problem, also known as the square peg problem or the Toeplitz' conjecture, is an unsolved question in geometry: "Does every plane simple closed curve contain all four vertices of some square?"
 This is true if the curve is convex or piecewise smooth and in other special cases.
 The problem was proposed by Otto Toeplitz in 1911.
 Some early positive results were obtained by Arnold Emch and Lev Schnirelmann.
 s of 2016 the general case remains open.
