Let A be a C^*-algebra, then a state is a positive linear functional on A of norm 1.

A state diagram is a labeled directed graph together with state information that can be used to indicate that certain paths on in a system may be traversed only in a certain ...

The measurable space (S^',S^') into which a random variable from a probability space is a measurable function.

An operator relating the asymptotic state of a dynamical system governed by the Schrödinger equation ihd/(dt)psi(t)=Hpsi(t) to its original asymptotic state.

Baud rate is a measure of the number of times per second a signal in a communications channel changes state. The state is usually voltage level, frequency, or phase angle.

An operator relating the past asymptotic state of a dynamical system governed by the Schrödinger equation id/(dt)psi(t)=Hpsi(t) to its future asymptotic state.

One baud is defined as the state of a signal in a communication channel changing once per second.

The characteristic escape rate from a stable state of a potential in the absence of signal.

An immediate consequence of a result already proved. Corollaries usually state more complicated theorems in a language simpler to use and apply.

The term "transition matrix" is used in a number of different contexts in mathematics. In linear algebra, it is sometimes used to mean a change of coordinates matrix. In the ...
