Periodic boundary value problems for impulsive integro-differential equations of mixed type

Oscillatory and Periodic Solutions of Impulsive Differential Equations with Piecewise Constant Argument

“…As we know, impulsive differential equations with piecewise constant arguments are studied in a few papers [16,20]. In [16], Li and Shen considered the periodic value problem…”

Advanced Impulsive Differential Equations With Piecewise Constant Arguments

“…Impulses can make unstable systems stable and stable systems can become unstable after impulse effects [4,16,23]. To the best of our knowledge, there are only a few papers involving impulsive differential equations with piecewise constant arguments [15,26]. In [15], Li and Shen considered the problem…”

Some new results for BVPs of first-order nonlinear integro-differential equations of volterra type

“…For the recent developments involving existence of solutions to BVPs for integro-differential equations and impulsive integro-differential equations we can refer to [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. So far the main method appeared in the references to guarantee the existence of solutions is the method of upper and low solutions.…”
