https://en.wikipedia.org/wiki/Prime-counting%20function | In mathematics, the prime-counting function is the function counting the number of prime numbers less than or equal to some real number x. It is denoted by (x) (unrelated to the number ).
Growth rate
Of great interest in number theory is the growth rate of the prime-counting function. It was conjectured in the end of... |
https://en.wikipedia.org/wiki/Common%20name | In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is often based in... |
https://en.wikipedia.org/wiki/Algebra%20homomorphism | In mathematics, an algebra homomorphism is a homomorphism between two algebras. More precisely, if A and B are algebras over a field (or a ring) K, it is a function such that, for all k in K and x, y in A, one has
The first two conditions say that F is a K-linear map, and the last condition says that F preserv... |

https://en.wikipedia.org/wiki/Sociable%20number | In mathematics, sociable numbers are numbers whose aliquot sums form a periodic sequence. They are generalizations of the concepts of perfect numbers and amicable numbers. The first two sociable sequences, or sociable chains, were discovered and named by the Belgian mathematician Paul Poulet in 1918. In a sociable sequ... |
https://en.wikipedia.org/wiki/Industrial%20data%20processing | Industrial data processing is a branch of applied computer science that covers the area of design and programming of computerized systems which are not computers as such — often referred to as embedded systems (PLCs, automated systems, intelligent instruments, etc.). The products concerned contain at least one micropr... |
https://en.wikipedia.org/wiki/Rate%20%28mathematics%29 | In mathematics, a rate is the quotient of two quantities in different units of measurement, often represented as a fraction. If the divisor (or fraction denominator) in the rate is equal to one expressed as a single unit, and if it is assumed that this quantity can be changed systematically (i.e., is an independent var... |
https://en.wikipedia.org/wiki/Primitive%20element | In mathematics, the term primitive element can mean:
Primitive root modulo n, in number theory
Primitive element (field theory), an element that generates a given field extension
Primitive element (finite field), an element that generates the multiplicative group of a finite field
Primitive element (lattice), an el... |
https://en.wikipedia.org/wiki/Hereditarily%20finite%20set | In mathematics and set theory, hereditarily finite sets are defined as finite sets whose elements are all hereditarily finite sets. In other words, the set itself is finite, and all of its elements are finite sets, recursively all the way down to the empty set.
Formal definition
A recursive definition of well-founded ... |
https://en.wikipedia.org/wiki/Quotient | In arithmetic, a quotient (from 'how many times', pronounced ) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics. It has two definitions: either the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of a... |

https://en.wikipedia.org/wiki/Aromatic%20amine | In organic chemistry, an aromatic amine is an organic compound consisting of an aromatic ring attached to an amine. It is a broad class of compounds that encompasses anilines, but also many more complex aromatic rings and many amine substituents beyond . Such compounds occur widely.
Aromatic amines are widely used a... |
