Delay differential equations (DDEs) extend classical ordinary differential equations by incorporating dependencies on past states. This inclusion of time delays is critical for accurately modelling ...

Much of the theory and applications of delay differential equations (DDEs) focuses on constant and time-dependent time delays. How- ever, many delays in physical (e.g. action-at-a-distance ...

Initial value problems for first order partial functional almost linear equations with unbounded delay are considered. The functional dependence is represented by the generalized Hale operator with ...
