31Scalar-tensor theory — Scalar tensor theories are theories that include a scalar field as well as a tensor field to represent an interaction, especially the gravitational one. Tensor fields and field theory Modern physics tries to derive all physical theories from as… …
32Minor (graph theory) — In graph theory, an undirected graph H is called a minor of the graph G if H is isomorphic to a graph that can be obtained by zero or more edge contractions on a subgraph of G. The theory of graph minors began with Wagner s theorem that a graph… …
33Nonsymmetric gravitational theory — In theoretical physics, the nonsymmetric gravitational theory[1] (NGT) of John Moffat is a classical theory of gravitation which tries to explain the observation of the flat rotation curves of galaxies. In general relativity, the gravitational… …
34Info-gap decision theory — is a non probabilistic decision theory that seeks to optimize robustness to failure – or opportuneness for windfall – under severe uncertainty,[1][2] in particular applying sensitivity analysis of the stability radius type[3] to perturbations in… …
35Bar product (coding theory) — In information theory, the bar product of two linear codes C 2 sube; C 1 is defined as:C 1 | C 2 = { (c 1|c 1+c 2) : c 1 in C 1, c 2 in C 2 } ,where ( a | b ) denotes the concatenation of a and b . If the code words in C 1 are of length n , then… …
36Chess theory — The game of chess is commonly divided into three phases: the opening, middlegame, and endgame.[1] As to each of these phases, especially the opening and endgame, there is a large body of theory as how the game should be played. Those who write… …
37Small cancellation theory — In the mathematical subject of group theory, small cancellation theory studies groups given by group presentations satisfying small cancellation conditions, that is where defining relations have small overlaps with each other. It turns out that… …
38Morse theory — Morse function redirects here. In another context, a Morse function can also mean an anharmonic oscillator: see Morse potential In differential topology, the techniques of Morse theory give a very direct way of analyzing the topology of a… …
39Geometric invariant theory — In mathematics Geometric invariant theory (or GIT) is a method for constructing quotients by group actions in algebraic geometry, used to construct moduli spaces. It was developed by David Mumford in 1965, using ideas from the paper… …
40Cumulative prospect theory — Daniel Kahneman Cumulative prospect theory (CPT) is a model for descriptive decisions under risk which was introduced by Amos Tversky and Daniel Kahneman in 1992 (Tversky, Kahneman, 1992). It is a further development and variant of prospect… …
