A global stability criterion for a family of delayed population models
Liz, Eduardo; Pinto Jiménez, Manuel; Tkachenko, Victor; Trofimchuk, Sergei (American Mathematical Society, 2005)For a family of singlespecies delayed population models, a new global stability condition is found. This condition is sharp and can be applied in both monotone and nonmonotone cases. Moreover, the consideration of variable ... 
A GrobmanHartman theorem for differential equations with piecewise constant arguments of mixed type
Pinto Jiménez, Manuel; Robledo Veloso, Gonzalo (European Mathematical SOC, 2018)We obtain sufficient conditions for the existence of a uniformly and Holder continuous homeomorphism between the solutions of a linear differential system with piecewise constant argument of generalized type and the solutions ... 
A Grobman–Hartman Theorem for Differential Equations with Piecewise Constant Arguments of Mixed Type

A new class of differential equations with impulses at instants dependent on preceding pulses. Applications to management of renewable resources
Córdova Lepe, Fernando; Pinto Jiménez, Manuel; González Olivares, Eduardo (2012)In this paper, a new type of mathematical model to represent certain processes with impulsive dynamic behavior is introduced. The main assumption is that the next impulse time is determined by three fundamental elements: ...

We study the existence of almost periodic solutions for semilinear abstract parabolic evolution equations with impulse action at statedependent moments. In particular, we present conditions excluding ...

Asymptotic integration of a linear fourth order differential equation of Poincare type
Coronel, Aníbal; Huancas, Fernando; Pinto Jiménez, Manuel (University Szeged, 2015)This article deals with the asymptotic behavior of nonoscillatory solutions of fourth order linear differential equation where the coefficients are perturbations of constants. We define a change of variable and deduce that ...
