<p>The application of generalized and fractional derivatives such as Caputo and Riemann-Liouville derivatives has witnessed a dramatic increase in recent years. This reprint focuses on related theoretical and applied research in areas such as the stability of time series Lotka-Volterra systems distributed delays Fornberg-Whitham equations abstract evolution and fractional wave equations cantilever beams and fractional Riccati and Volterra equations as well as fractional visco-elasto-plasticity spectral theory for fractional Sturm-Liouville problems generalized differential equations Mittag-Leffler functions and fractional Laplacians.</p>
