In General > s.a. computation;
modified classical mechanics; probability and statistics

process.
* Idea: Stochastic dynamics
ideas can be used directly to model physical processes, or applied to derive
kinetic equations, such as the Boltzmann, Vlasov, Fokker-Planck, Landau, and
quantum Neumann-Liouville equations.

Noise and Other Related Topics > s.a. Feynman-Kac
Formula.
* Types of noise: Stationary/non-stationary;
Ergodic; Gaussian.
* Gaussian: The autocorrelation function contains all the information
on the noise.
* Noise level: Defined
as a function of frequency by hn(f):=
[f Sn(f)]1/2,
where Sn(f)
is the spectral density.

Markov Chain or Process > s.a. formulations
of quantum mechanics; Master Equation; random
process [walk].
* Idea: A process in
which a system evolves through a sequence of steps in some set of possible
states, the probability of it going to a certain
state
in the next step depending only on the state it is in (no memory); It
is characterized by a transition matrix T such that Tij
0
for all
i, j and
i Tij =
1 for all j.
* History: Introduced by
Markov in 1906, who just wanted to show that independence was not needed for
the law of large numbers; An example he considered
was the
alternation of consonants and vowels in Pushkin's Eugene Onegin, which
he described as a two-state Markov chain; Soon Poincaré was
studying
Markov chains on finite groups to study card shuffling; Today they
are in all
applied sciences, from population biology to communication networks,
diffusion models, or social mobility.

Specific Types of Systems > s.a. differential
equations; fluctuations; probability
in physics.
* Non-Markovian processes:
Two broad types are history-dependent processes (which may be formally turned
into Markovian processes by redefining the configurations to include the
relevant part of the history), and open systems (whose dynamics depends on
their environment).
