rank of theory
81Nine-rank system — The nine rank system (Chinese: 九品中正制; pinyin: jiǔ pǐn zhōng zhèng zhī or Chinese: 九品官人法; pinyin: jiǔ pǐn guān rén fǎ), or much less commonly nine grade controller system, was a civil service nomination system during the Three Kingdoms and the… …
82Order (ring theory) — In mathematics, an order in the sense of ring theory is a subring of a ring R that satisfies the conditions R is a ring which is a finite dimensional algebra over the rational number field spans R over , so that …
83Journal of Economic Theory — The Journal of Economic Theory , often referred to as JET , is an important scholarly journal in the field of economics. Although the journal was originally intended as a specialty journal in mathematical economics, JET is now generally regarded… …
84Contiguity (probability theory) — In probability theory, two sequences of probability measures are said to be contiguous if asymptotically they share the same support. Thus the notion of contiguity extends the concept of absolute continuity to the sequences of measures. The… …
85classification theory — principles governing the organization of objects into groups according to their similarities and differences or their relation to a set of criteria. Classification theory has applications in all branches of knowledge, especially the… …
86Circuit rank — The circuit rank of a graph G (also known as the cyclomatic number of G) is the minimum number r of edges to remove from the graph to make it cycle free. It has the formula r = m − n + c, where m is the number |E(G)| of edges in G, n is the… …

88Acoustic theory — is the field relating to mathematical description of sound waves. It is derived from fluid dynamics. See acoustics for the engineering approach.The propagation of sound waves in a fluid (such as air) can be modeled by an equation of motion… …
89Growth rate (group theory) — In group theory, the growth rate of a group with respect to a symmetric generating set describes the size of balls in the group. Every element in the group can be written as a product of generators, and the growth rate counts the number of… …
90Spectral theory of compact operators — In functional analysis, compact operators are linear operators that map bounded sets to precompact ones. Compact operators acting on a Hilbert space H is the closure of finite rank operators in the uniform operator topology. In general, operators …
