Differential equations with impulses arise as models of many evolving processes that are
subject to abrupt changes, such as shocks, harvesting, and natural disasters. These …

Impulsive differential equations are a basic instrument to study the dynamics of processes
that are subjected to sudden changes in their states. Recent development in the qualitative …

This paper provides existence results for the nonlinear impulsive periodic boundary value
problemwhere f∈ Car ([0, T]× R2) and Ji, Mi∈ C (R). The basic assumption is the existence …

This paper deals with a new existence theory for single and multiple positive periodic

We study the existence of mild and classical solutions for an abstract second‐order
impulsive Cauchy problem modeled in the form u¨(t)= A u (t)+ f (t, u (t), u˙(t)), t∈(− T 0, T 1) …

This paper studies the existence of extremal solutions for a class of singular boundary value
problems of second order impulsive differential equations. By using the method of upper and …

This paper is concerned with the solvability of periodic boundary value problems for
nonlinear impulsive functional differential equations We obtain sufficient conditions for the …

In this paper, using the lower/upper functions argument, we establish new existence results
for the nonlinear impulsive periodic boundary value problem u= f (t, u, u),(1.1) u (ti+)= Ji (u …
