Oscillation theory of impulsive differential equations
The attraction of oscillation theory is linked rather strongly with the occurrence of new objects to be investigated. Such fast development can be observed in studying the oscillation properties of differential equations with deviating argument after 1970, as well as in the investigations in this direction for neutral equations after 1980.

14.5 Oscillations in an LC Circuit
It is worth noting that both capacitors and inductors store energy, in their electric and magnetic fields, respectively. A circuit containing both an inductor (L) and a capacitor (C) …
RENORMALIZED OSCILLATION THEORY FOR DIRAC …
Using standard oscillation theory would mean to count zeros of components of solutions of the Dirac equation. Unfortunately this approach soon leads into severe troubles: (i). Components of solutions might vanish identically on some intervals. (ii). Zeros of components of solutions are not monotone with respect to the spec-tral parameter.

Electromagnetic oscillations begin when the switch is closed. The capacitor is fully charged initially. (b) Damped oscillations of the capacitor charge are shown in this curve of charge versus time, or q versus t. The capacitor contains a charge (q_0) before the switch is closed. This equation is analogous to

At this point, (C) begins to charge toward (V_{cc}) through (R). When the capacitor voltage reaches 2/3 (V_{cc}), the Threshold comparator fires, setting the output low and turning on the Discharge transistor. This drains the timing capacitor, and the circuit is ready for the application of a new input pulse.
