Analytical and numerical analysis of damped harmonic oscillator model with nonlocal operators
Nonlocal operators with different kernels were used here to obtain more general harmonic oscillator models. Power law, exponential decay, and the generalized Mittag-Leffler kernels with Delta-Dirac property have been utilized in this process.
