STABILITY AND DYNAMICS OF A WEAK VISCOELASTIC SYSTEM WITH MEMORY AND NONLINEAR TIME-VARYING DELAY

摘要

This paper is concerned with the stability and dynamics of a weak viscoelastic system with nonlinear time-varying delay. By imposing appropriate assumptions on the memory and sub-linear delay operator, we prove the global well-posedness and stability which generates a gradient system. The gradient system possesses finite fractal dimensional global and exponential attractors with unstable manifold structure. Moreover, the effect and balance between damping and time-varying delay are also presented.
