On the advanced balanced pantograph equation
Communications on Pure and Applied AnalysisThe paper is concerned with the advanced balanced pantograph equation \[ y'(x)+y(x)=\displaystyle\sum_{k=1}^m p_k y(a_kx),\tag{1} \] where \(p_k>0\) for \(k=1,\ldots,m\), \(\sum_{k=1}^m p_k=1\), and ...

On Bounded Solutions of the Balanced Generalized Pantograph Equation [PDF]
, 2008 The question about the existence and characterization of bounded solutions to linear functional-differential equations with both advanced and delayed arguments was posed in early 1970s by T. Kato in connection with the analysis of the pantograph equation, y'(x)=ay(qx)+by(x).

Advanced Materials Technologies, Volume 10, Issue 13, July 8, 2025.This study presents a braided fiber‐reinforced sleeve that amplifies strain in soft materials, enhancing their performance in stretchable devices like sensors and energy harvesters. By reinforcing and elongating encased materials, the sleeve increases the “effective” strain.

Discretized Stability and Error Growth of The Nonautonomous Pantograph Equation [PDF]
SIAM Journal on Numerical Analysis, 2005 The paper deals with stability properties of Runge-Kutta methods for the pantograph equation \[ y^\prime(t) = f(t,y(t),y(qt),y^\prime(qt)),\quad t > 0, \] \[ y(0) = y_0. \] The authors obtain sufficient and necessary conditions for the asymptotic stability of the numerical solution and an upper bound for the error growth is obtained.
