Das Wachstum ganzer Lösungen gewisser linearer Funktional-Differentialgleichungen.
Delay differential systems with discontinuous initial data and existence and uniqueness theorems for systems with impulse and delay.
Delay makes problems in population modelling
Differentiable semiflows for differential equations with state-dependent delays.
Discontinuous solutions of neutral functional differential equations.
The fundamental theory of existence, uniqueness and continuous differentiability of Lp-solutions for Neutral Functional Differential Equations is presented. Also, the spectrum of the solution operator of general autonomous linear NFDEs is described. Finally, an extension of Hartman Grobman Theorem on local conjugacy near a hyperbolic equilibrium is proved.
