Almost Periodicity in Time-Dependent and State-Dependent Delay Differential Equations

Solving Coupled Impulsive Fractional Differential Equations With Caputo-Hadamard Derivatives in Phase Spaces

“…Many papers have addressed this purpose, either by introducing the Caputo functional fractional operators or by introducing other fractional operators with state-dependent delays. For more information, see [24][25][26][27][28][29][30][31][32][33]. According to our knowledge, there are no works in the literature that discuss Caputo-Hadamard fractional (CHF) order functional DEs with state-dependent delay and impulses.…”
