Abstract To avoid the unstable phenomena caused by time delays and perturbations, we investigate the sufficient conditions to ensure the global exponential robust stability with a convergence rate… (More)

Abstract In this work, we analyze the new generalized Emden–Fowler equation with neutral type delays: r ( t ) | Z ′ ( t ) | α - 1 Z ′ ( t ) ′ + q ( t ) | x ( σ ( t ) ) | β - 1 x ( σ ( t ) ) = 0 ,… (More)

By means of novel analytical techniques, we have established several new oscillation criteria for the generalized Emden-Fowler dynamic equation on a time scale , that is, , with respect to the case… (More)

In this paper, we have introduced the S-type distributed delays into the Cohen-Grossberg neural networks since this type of delays may arise in practice and is more general than usual type of… (More)
During the past three decades, global optimization problems (including single-objective optimization problems (SOP) and multi-objective optimization problems (MOP)) have been intensively studied not… (More)
