A History of Feynman's Sum over Histories in Quantum Mechanics
Akira Inomata, Georg Junker
A history of Feynman's sum over histories is presented in brief. A focus is placed on the progress of path-integration techniques for exactly path-integrable problems in quantum me…

Quantum and classical stochastic dynamics: Exactly solvable models by supersymmetric methods
Georg Junker
A supersymmetric method for the construction of so-called conditionally exactly solvable quantum systems is reviewed and extended to classical stochastic dynamical systems characte…

Coherent-state path-integral approach for constrained fermion systems
Georg Junker, John R. Klauder
The coherent-state path-integral representation for the propagator of fermionic systems subjected to first-class constraints is constructed. As in the bosonic case the importance o…
