Polynesian languages The Polynesian languages are a language family spoken in the region known as Polynesia. They are classified as part of the Austronesian family, belonging to the Eastern Eastern Malayo-Polynesian branch of that family.
Polynesian mythology Polynesia (meaning "many islands" in Greek) is a triangular grouping of Central and South Pacific Ocean island archipelagos settled by seafaring voyagers from the original heartland in Tonga and Samoa. Prior to the 15th century AD, Polynesian people fanned out to the east, to the Cook Islands, and from there to other groups such as Tahiti and the Marquesas.
Polynesian outlier Polynesian outliers are a number of culturally Polynesian islands which lie in geographic or political Melanesia and Micronesia. Based on archaeological and linguistic analysis, these islands are believed to have been colonized by seafaring Polynesians, mostly from the area of Tonga, Samoa and Tuvalu.
Polynesian Rat The Polynesian Rat, Pacific Rat, or Māori Rat (Rattus exulans), known to the Māori as kiore, is the third most widespread species of rat in the world behind the Brown Rat and Black Rat. The kiore orginates in Southeat Asia but, like its cousins, has become well traveled - infiltrating most Polynesian islands, New Zealand, Fiji, and even Hawaii.
Polynesian sandpiper The two to four species of Polynesian sandpipers, the only members of the genus Prosobonia, are small wading birds confined to remote Pacific islands of French Polynesia. Only one species now exist, and it is rare and little known.
Polynesian Triangle The Polynesian Triangle is a region of the Pacific Ocean anchored by three island groups: Hawai'i, Easter Island (Rapa Nui) and New Zealand. The many island cultures within this vast triangle speak Polynesian languages which are classified by linguists as part of the Malayo-Polynesian subgroup and thus ultimately derive from the proto-Austronesian language spoken in Southeast Asia 5000 years ago.
Polyneutron Polyneutrons are a hypothetical particle state of matter composed of multiple neutrons in a bound system similar to an atomic nucleus but with no net electric charge. Polyneutrons are also known as neutron droplets, neutron clusters, or neutrium (Nt).
Polynomial In mathematics, a polynomial is an expression in which one or more variables and constants are combined using only addition, subtraction, multiplication, and non-negative whole number exponents (raising to a power). Thus,
Polynomial expansion In mathematics, an expansion of a product of sums expresses it as a sum of products by using the fact that multiplication distributes over addition. Expansions of polynomials are obtained by multiplying together their factors, which results in a sum of terms with variables raised to different degrees.
Polynomial interpolation In the mathematical subfield of numerical analysis, polynomial interpolation is the interpolation of a given data set by a polynomial. In other words, given some data points (such as obtained by sampling), the aim is to find a polynomial which goes exactly through these points.
Polynomial long division In algebra, polynomial long division is an algorithm for dividing a polynomial by another polynomial of lower degree, a generalised version of the familiar arithmetic technique called long division. It can be done easily by hand, because it separates an otherwise complex division problem into smaller ones.
Polynomial time In computational complexity theory, polynomial time refers to the computation time of a problem where the time, m(n), is no greater than a polynomial function of the problem size, n. Any given abstract machine will have a complexity class corresponding to the problems which can be solved in polynomial time on that machine.
Polynomial-time reduction In computational complexity theory a polynomial-time reduction is a reduction which is computable by a deterministic Turing machine in polynomial time. If it is a many-one reduction, it is called a polynomial-time many-one reduction, polynomial transformation, or Karp reduction.
Polynormal subgroup In mathematics, in the field of group theory, a subgroup of a group is said to be polynormal if its closure under conjugation by any element of the group can also be achieved via closure by conjugation by some element in the subgroup generated.
