A dynamical model of SARS-CoV-2 in fractional derivative using the cases of
coronavirus of the fourth wave is presented. We construct basically the model in an
integer case, and later it is extended to a fractional-order system by applying the …

We investigate the Hilfer-type operator within the topic of tempered fractional
calculus with respect to functions. This operator, the tempered Ψ-Hilfer derivative, is
defined for the first time here, and its fundamental properties are studied, such as …

Fractional-order systems have proved to be accurate in describing the spread of the
COVID-19 pandemic by virtue of their capability to include the memory effects into
the system dynamics. This manuscript presents a novel fractional discrete-time …

The existence of a mild solution for nonlinear Hilfer fractional stochastic differential
equations of the Sobolev type with non-instantaneous impulse in Hilbert space is
investigated in this study. For nonlinear Hilfer fractional stochastic differential …
