Random Processes  

Randomness in Mathematics and in General > s.a. matrices; probability.
@ General references: Shale JFA(79) [functions]; Compagner AJP(91) [definitions]; Bennett 98 [history]; Eagle BJPS(05) [as unpredictability].
@ Random numbers: Vattulainen et al PRL(94) [tests]; Stefanov et al qp/99 [generators, using quantum mechanics].

Random Process > s.a. computing; Fiber [fiber process]; fractal; stochastic processes.
* Idea: (The most) random (infinite) sequences are those which cannot be described by algorithms shorter than the sequances themselves (Bernoulli chain/sequence).
* Examples: No computable number is random (see ).
* Remark: It is impossible to prove that any given sequence was generated by a random process.

Random Walk > s.a. diffusion.
* Idea: A probability measure on the space of all paths on a space; For example, Brownian motion.
* Specification: Can be assigned as a transition probability from each incomplete, n-step path, to each extension to n+1 steps; A simple type of situation is a Markov process, in which the probability only depends on the n-th configuration.
* Displacement: In a space of Hausdorff dim d, the mean square displacement after N steps is D2 N 2/d; The planar (d = 2) self-avoiding walk has rms displacement exponent 3/4 (long conjectured, proved in 2001).
* Applications: Used to sample a space of states in randomized algorithms.
