Large time behavior of solutions to a nonlinear hyperbolic relaxation system with slowly decaying data
Ikki Fukuda
We consider the large time asymptotic behavior of the global solutions to the initial value problem for the nonlinear damped wave equation with slowly decaying initial data. When t…

Asymptotic stability and stability switching for a system of delay differential equations
Wataru Saito, Ikki Fukuda
In this paper, we consider the asymptotic stability for a system of linear delay differential equations. By analysing of the characteristic equation in detail, we have established…
