The chain rule for Kolmogorovcomplexity is an analogue of the chain rule for information entropy , which states math H X,Y H X H Y X math That is, the combined randomness of two sequences X and Y is the sum of the randomness of X plus whatever randomness is left in Y once we know X . This follows immediately from the definitions of conditional entropy conditional and joint entropy fact from probability theory that the joint probability is the product of the marginal probability marginal and conditional probability math P X,Y P X P Y X , math The equivalent statement for Kolmogorovcomplexity does not hold exactly it is only true up to a logarithm ic factor math K X,Y K X K Y X O log K X,Y math An exact version, KP X ,  Y     KP X     KP Y X     O 1 , holds for the prefix complexity KP , where X is a shortest program for X . It states that the shortest program to reproduce X and Y is using a program to reproduce X and a program to reproduce Y given X , plus Big O notation at most a logarithmic factor. Using this statement one can define Mutual information Absolute mutual information an analogue of mutual information for Kolmogorovcomplexity . Proof The direction is obvious we can write a program to produce x and y by concatenating a program to produce x , a program to produce y given access to x , and whence the log term the length of one of the programs, so that we know where to separate the two programs for x and y x log K x ,  y upper bounds this length . The direction is rather more difficult. The key to the proof is the construction of the set math A u,z K u,z le K x,y math that is, the construction of the set of all pairs math u,z math such that the shortest input for a universal Turing machine that produces math u,z math and some way to distinguish math u math from math z math is shorter than the shortest producing math x,y math ... last Li first Ming coauthors Vitá nyi, Paul title An introduction to Kolmogorovcomplexity and its ... more details

Andrey KolmogorovKolmogorov microscales are the smallest scale ratio scale s in Turbulence turbulent flow . They are defined ref Landahl, M.T. & E. Mollo Christensen. Turbulence and Random Processes in Fluid Mechanics. Cambridge, 2ed, 1992. ref by class wikitable Kolmogorov length scale math eta left frac nu 3 epsilon right 1 4 math Kolmogorov time scale math tau eta left frac nu epsilon right 1 2 math Kolmogorov velocity scale math u eta left nu epsilon right 1 4 math where math epsilon math is the average rate of energy dissipation per unit mass, and math nu math is the kinematic viscosity of the fluid. In his 1941 theory, A. N. Kolmogorov introduced the idea that the smallest scales of turbulence are universal similar for every turbulent flow and that they depend only on math epsilon math and math nu math . The definitions of the Kolmogorov microscales can be obtained using this idea and dimensional analysis . Since the dimension of kinematic viscosity is length sup 2 sup time, and the dimension of the energy dissipation rate per unit mass is length sup 2 sup time sup 3 sup , the only combination that has the dimension of time is math tau eta nu epsilon 1 2 math which is the Kolmorogov time scale. Similarly, the Kolmogorov length scale is the only combination of math epsilon math and math nu math that has dimension of length. The Kolmogorov 1941 theory is a mean field theory since it assumes that the relevant dynamical parameter is the mean energy dissipation rate. In fluid turbulence , the energy dissipation rate fluctuates in space and time, so it is possible to think of the microscales as quantities that also vary in space and time. However, standard practice is to use mean field values since they represent the typical values of the smallest scales in a given flow ...

In computational complexity theory complexity theory , ZPL Zero error Probabilistic Logarithmic space is the set of problems solvable by a probabilistic Turing machine which always yields the correct answer and uses logarithmic space on average. Probabilistic algorithms that always give the correct answer are called Las Vegas algorithm s. Unlike its deterministic counterpart L complexity L , a ZPL machine can potentially use exponential time by exploiting randomness. If ZPL is restricted to polynomial time, we get the more interesting class ZPLP complexity ZPLP . A surprising result is that ZPL is equal to both RL complexity RL and NL complexity NL thus, if a problem can be solved in logarithmic space with nondeterminism or with one sided error, it can be solved with no error and logarithmic space on average.
