“…It is well-known that the classical fractional differential equations can have asymptotically stable solutions, but not exponentially. Some sufficient conditions for the exponential stability of solutions of fractionally perturbed ODEs with tempered Riemann-Liouville fractional integrals and several constant delays are proved in the papers [28,29,30,31]. A new type of derivative, called the Hilfer fractional derivative, was defined by R. Hilfer [16].…”
