Abstract:
The motion of pulses is considered on a star-shaped metric graph composed of paths with different widths. We derive the equation that describes the motion of a pulse based on these widths. As applications, we demonstrate the motion towards the junction for pulses described by the FitzHugh-Nagumo equation and the Gierer-Meinhardt equation.
