111Calabi–Yau manifold — In mathematics, Calabi ndash;Yau manifolds are compact Kähler manifolds whose canonical bundle is trivial. They were named Calabi ndash;Yau spaces by physicists in 1985, [cite journal | author = Candelas, Horowitz, Strominger and Witten | year =… …
112Hidden node problem — In wireless networking, the hidden node problem occurs when a Node (networking) node is visible from a wireless access point (AP), but not from other nodes communicating with said AP. This leads to difficulties in media access control.… …
113Lattice (order) — See also: Lattice (group) The name lattice is suggested by the form of the Hasse diagram depicting it. Shown here is the lattice of partitions of a four element set {1,2,3,4}, ordered by the relation is a refinement of . In mathematics, a… …
114Sard's theorem — Sard s theorem, also known as Sard s lemma or the Morse–Sard theorem, is a result in mathematical analysis which asserts that the image of the set of critical points of a smooth function f from one Euclidean space or manifold to another has… …
115Supramolecular chemistry — refers to the area of chemistry that focuses on the noncovalent bonding interactions of molecules. [cite journal | author=Lehn JM | title=Supramolecular chemistry | journal=Science | volume=260 | issue=5115 | year=1993 | pages=1762–3 |… …
116PCF theory — is the name of a mathematical theory, introduced by Saharon Shelah (1978), that deals with the cofinality of the ultraproducts of ordered sets. It gives strong upper bounds on the cardinalities of power sets of singular cardinals, and has… …
117System of imprimitivity — The concept of system of imprimitivity is used in mathematics, particularly in algebra and analysis, both within the context of the theory of group representations. It was used by George Mackey as the basis for his theory of induced unitary… …
118T-norm — In mathematics, a t norm (also T norm or, unabbreviated, triangular norm) is a kind of binary operation used in the framework of probabilistic metric spaces and in multi valued logic, specifically in fuzzy logic. A t norm generalizes intersection …
119Neumann series — A Neumann series is a mathematical series of the form where T is an operator. Hence, Tn is a mathematical notation for n consecutive operations of the operator T. This generalizes the geometric series. The series is named after the mathematician… …
120Determinacy — Determined redirects here. For the 2005 heavy metal song, see Determined (song). For other uses, see Indeterminacy (disambiguation). In set theory, a branch of mathematics, determinacy is the study of under what circumstances one or the other… …
