Quasi-periodic solutions for differential equations with an elliptic-type degenerate equilibrium point under small perturbations

Xuemei Li, Zaijiu Shang

This work focuses on the existence of quasi-periodic solutions for ordinary and delay differential equations (ODEs and DDEs for short) with an elliptic-type degenerate equilibrium…
