Query: Chimera states on the surface of a sphere   A chimera state is a spatiotemporal pattern in which a network of identical
coupled oscillators exhibits coexisting regions of asynchronous and synchronous
oscillation. Two distinct classes of chimera states have been shown to exist:
"spots" and "spirals." Here we study coupled oscillators on the surface of a
sphere, a single system in which both spot and spiral chimera states appear. We
present an analysis of the birth and death of spiral chimera states and show
that although they coexist with spot chimeras, they are stable in disjoint
regions of parameter space.
