Generated Dynamics,se elements as part of the dynamics. The short time steps are captured by a time homogeneous generator resulting in differential equations in continuous time. States can be configurations, probabilities or pre-probabilities for configurations. We discuss some simple prototypical systems and comment纠缠,缠绕 发表于 2025-3-23 22:32:39
Formal Solutions,e advantages as a starting point for approximate methods. In rare cases they even allow for explicit solutions. The analytic formal solutions by generating functionals (path integrals, partition sums) are most convenient as starting points for modeling systems. They provide a basis for interpretingcardiovascular 发表于 2025-3-24 06:23:04

Observables, States, Entropy and Generating Functionals,nsity operators) included with compact and flexible ways of calculation. We introduce the notion of entropy as a dispersion measure and consider its time evolution in Markov and quantum processes. We consider limits of stationarity and cross-over between different types of dynamics by taking systemJogging 发表于 2025-3-24 11:30:10
Symmetries and Breaking of Symmetries,ies which are spherical symmetric. If one manages to find coordinates fitting to symmetries, some of them disappear from the invariant functions and this reduces the calculation task drastically. The same idea is behind the use of symmetries in representation theory to classify (and thus simplify thPedagogy 发表于 2025-3-24 16:14:00

Textbook 2016ersible stochastic processes generated by one-step unitary operators, while Markov processes are irreversible stochastic processes generated by one-step stochastic operators. The characteristic feature of quantum processes are oscillations, interference, lots of stationary states in bounded systems
