Kraft's inequality limits the lengths of codewords in a prefix code: if one takes an exponential of the length of each valid codeword, the resulting set of values must look like a probability mass function, that is, it must have total measure less than or equal to one. Kraft's inequality can be thought of in terms of a constrained budget to be ...
In information theory, the Kraft–McMillan theorem establishes that any directly decodable coding scheme for coding a message to identify one value out of a set of possibilities {, …,} can be seen as representing an implicit probability distribution () = over {, …,}, where is the length of the code for in bits.
McMillan was born in Minneapolis, Minnesota, in 1915, the only child of Franklin Richardson McMillan, a civil engineer, and Luvena Lucille Brockway McMillan, a schoolteacher. [3] He received his B.S. in 1936 and a Ph.D. 1939 from Massachusetts Institute of Technology (MIT) on a thesis entitled The calculus of discrete homogenous chaos ...
The Shannon–McMillan–Breiman theorem, due to Claude Shannon, Brockway McMillan, and Leo Breiman, states that we have convergence in the sense of L1. [2] Chung Kai-lai generalized this to the case where X {\displaystyle X} may take value in a set of countable infinity, provided that the entropy rate is still finite.
Call a full subtree of height whose leaves are a subset of the leaves of the full binary tree of depth , an -triangle. Identify a codeword of length l {\displaystyle l} with a node in the tree at depth l {\displaystyle l} , as usual, and also with the ( l m − l ) {\displaystyle (l_{m}-l)} -triangle rooted at that node.

The Poincaré–Bendixson theorem, which says an integral curve that does not end in a singular point has a limit cycle, was first proved by Henri Poincaré, but a more rigorous proof with weaker hypotheses was given by Bendixson in 1901. In 1902, he derived Bendixson's inequality, which puts bounds on the eigenvalues of real matrices.
