Morse potential, symmetric Morse potential and bracketed bound-state energies

For the needs of non-perturbative quantum theory, an upgraded concept of solvability is proposed. In a broader methodical context, the innovation involves Schrodinger equations which are piecewise analytic and piecewise sol...

Piecewise-Linear Vector Fields

Mathematical models describing real physical systems are based on smooth and continuous functions. However, for most systems it is impossible to find even a local analytic solution. The piecewise linear approximation represent a pos...

Zeta functions and topological entropy of periodic nonautonomous dynamical systems

In the setting of continuous piecewise monotone interval maps, we study the analytic properties of the zeta function of a periodic nonautonomous dynamical system. Based upon these properties we discuss the relationship between topol...
