Precomposition Precomposition with a function probably provides the most elementary notion of pullback: in simple terms, a function of a variable where itself is a function of ...

In mathematics, the Paley–Zygmund inequality bounds the probability that a positive random variable is small, in terms of its first two moments. The inequality was proved by Raymond Paley and Antoni Zygmund. Theorem: If Z ≥ 0 is a random variable with finite variance, and if , then Proof: First, The first addend is...

In algebra, Hall's universal group is a countable locally finite group, say U, which is uniquely characterized by the following properties. Every finite group G admits a monomorphism to U. All such monomorphisms are conjugate by inner automorphisms of U. It was defined by Philip Hall in 1959, and has the universa...

In geometry, the order-7 truncated triangular tiling, sometimes called the hyperbolic soccerball, is a semiregular tiling of the hyperbolic plane. There are two hexagons and one heptagon on each vertex, forming a pattern similar to a conventional soccer ball (truncated icosahedron) with heptagons in place of pentagons....
https://en.wikipedia.org/wiki/Supersingular%20K3%20surface
In algebraic geometry, a supersingular K3 surface is a K3 surface over a field k of characteristic p > 0 such that the slopes of Frobenius on the crystalline cohomology H2(X,W(k)) are all equal to 1. These have also been called Artin supersingular K3 surfaces. Supersingular K3 surfaces can be considered the most speci...
https://en.wikipedia.org/wiki/Snub%20%28geometry%29
In geometry, a snub is an operation applied to a polyhedron. The term originates from Kepler's names of two Archimedean solids, for the snub cube () and snub dodecahedron (). In general, snubs have chiral symmetry with two forms: with clockwise or counterclockwise orientation. By Kepler's names, a snub can be seen as a...
https://en.wikipedia.org/wiki/Carleman%27s%20condition
In mathematics, particularly, in analysis, Carleman's condition gives a sufficient condition for the determinacy of the moment problem. That is, if a measure satisfies Carleman's condition, there is no other measure having the same moments as The condition was discovered by Torsten Carleman in 1922. Hamburger mome...
