Rational pricing — is the assumption in financial economics that asset prices (and hence asset pricing models) will reflect the arbitrage free price of the asset as any deviation from this price will be arbitraged away . This assumption is useful in pricing fixed… … Wikipedia
Rational number — In mathematics, a rational number is any number that can be expressed as the quotient or fraction a/b of two integers, with the denominator b not equal to zero. Since b may be equal to 1, every integer is a rational number. The set of all… … Wikipedia
Rational mapping — In mathematics, in particular the subfield of algebraic geometry, a rational map is a kind of partial function between algebraic varieties. In this article we use the convention that varieties are irreducible.DefinitionA first attemptSuppose we… … Wikipedia
Equivalence relation — In mathematics, an equivalence relation is a binary relation between two elements of a set which groups them together as being equivalent in some way. Let a , b , and c be arbitrary elements of some set X . Then a b or a ≡ b denotes that a is… … Wikipedia
Equivalence class — This article is about equivalency in mathematics; for equivalency in music see equivalence class (music). In mathematics, given a set X and an equivalence relation on X, the equivalence class of an element a in X is the subset of all elements in… … Wikipedia
Rational homotopy theory — In mathematics, rational homotopy theory is the study of the rational homotopy type of a space, which means roughly that one ignores all torsion in the homotopy groups. It was started by Dennis Sullivan (1977) and Daniel Quillen (1969) … Wikipedia
Rational function — In mathematics, a rational function is any function which can be written as the ratio of two polynomial functions. DefinitionsIn the case of one variable, x , a rational function is a function of the form: f(x) = frac{P(x)}{Q(x)}where P and Q are … Wikipedia

Equivalence relations on algebraic cycles — In mathematics, equivalence relations of algebraic cycles are used in order to obtain a well working theory of algebraic cycles, including well defined intersection products. They also form an integral part of the category of pure… … Wikipedia
Adequate equivalence relation — In algebraic geometry, a branch of mathematics, an adequate equivalence relation is an equivalence relation on algebraic cycles of smooth projective varieties used to obtain a well working theory of such cycles, and in particular, well defined… … Wikipedia
Ricardian equivalence — Ricardian equivalence, (also known as the Barro Ricardo equivalence proposition) is an economic theory which suggests that it does not matter whether a government finances its spending with debt or tax increase, total level of demand in an… … Wikipedia
