Query: Hydrodynamic flow patterns and synchronization of beating cilia   We calculate the hydrodynamic flow field generated far from a cilium which is
attached to a surface and beats periodically. In the case of two beating cilia,
hydrodynamic interactions can lead to synchronization of the cilia, which are
nonlinear oscillators. We present a state diagram where synchronized states
occur as a function of distance of cilia and the relative orientation of their
beat. Synchronized states occur with different relative phases. In addition,
asynchronous solutions exist. Our work could be relevant for the synchronized
motion of cilia generating hydrodynamic flows on the surface of cells.
