Tobin's q [a] (or the q ratio, and Kaldor's v), is the ratio between a physical asset's market value and its replacement value.It was first introduced by Nicholas Kaldor in 1966 in his paper: Marginal Productivity and the Macro-Economic Theories of Distribution: Comment on Samuelson and Modigliani.
For price discrimination to succeed, a seller must have market power, such as a dominant market share, product uniqueness, sole pricing power, etc. [9] Some prices under price discrimination may be lower than the price charged by a single-price monopolist. Price discrimination can be utilized by a monopolist to recapture some deadweight loss.
An odds ratio (OR) is a statistic that quantifies the strength of the association between two events, A and B. The odds ratio is defined as the ratio of the odds of event A taking place in the presence of B, and the odds of A in the absence of B. Due to symmetry, odds ratio reciprocally calculates the ratio of the odds of B occurring in the presence of A, and the odds of B in the absence of A.
Thus, b q is a symmetric bilinear form over K with matrix A. Conversely, any symmetric bilinear form b defines a quadratic form q ( x ) = b ( x , x ) , {\displaystyle q(x)=b(x,x),} and these two processes are the inverses of each other.

Let p and q be polynomials with coefficients in an integral domain F, typically a field or the integers. A greatest common divisor of p and q is a polynomial d that divides p and q, and such that every common divisor of p and q also divides d.
The "Two-source Hypothesis" proposes that the Gospels of Matthew and Luke were written independently, each using Mark and a second hypothetical document called "Q" as a source.
The number π (/ p aɪ /; spelled out as "pi") is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159.The number π appears in many formulae across mathematics and physics.
