Spiral Waves in Oscillatory Media with Nonlocal Coupling

Gabriela Jaramillo from the University of Houston demonstrates, for a general oscillatory model with nonlocal coupling, the existence of spiral waves by first deriving an amplitude equation, then using the methods of multiple scales to identify terms in the spiral wave solutions to multiple orders, and finally numerically showing how nonlocal interactions shape the spirals.
