On the structure of steadily propagating rings of chemotactic bacteria.

The theoretical structure of steadily propagating cylindrically-symmetric rings of chemotactic bacteria is determined by solving the governing dynamical equations for the bacterial density distribution and the concentration of chemotactic agent. Accurate to first-order in the reciprocal of the radial distance from the axis of symmetry, the asymptotic solution obtained here can be employed for future comparison with measured experimental distributions.
