Oscillation criteria for functional differential equations
Electronic Journal of Differential Equations, 2005 Consider the first-order linear delay differential equation $$ x'(t)+p(t)x(au (t))=0,quad tgeq t_{0}, $$ and the second-order linear delay equation $$ x''(t)+p(t)x(au (t))=0,quad tgeq t_{0}, $$ where $p$ and $au $ are continuous functions on $[t_{0 ...

Continuous Runge–Kutta schemes for pantograph type delay differential equations
Partial Differential Equations in Applied MathematicsPantograph differential equations are important types of delay differential equations. Using continuous mono-implicit RK schemes, we propose a numerical method for numerically approximating pantograph delay differential equations that are reliable and ...

Hysteresis-Delay Differential Equations
, 2016 In this dissertation we study differential equations with both discontinuous hysteresis of non-ideal relay type and delay terms. We study general properties (existence and uniqueness of solutions) and focus on the stability of periodic solutions. We give an application for control theory.
