Velocity-Amplitude Relationship in the Gray-Scott Autowave Model in Isolated Conditions.

Velocity and amplitude are two basic characteristics of any autowave, and their relationship reflects the internal regulation of the autowave system. This study proposes an approach to approximately estimate steady velocity-amplitude (VA) relation without deriving separate formulas for and . The approach presumes constructing an which represents the "petal" form of phase trajectory and contains , , and a free parameter (parameters).
