Description
We show that D-branes and fluxes in minimal type 0A string theory can be identified with a subset of the solitons of the KdV hierarchy which is known to underlie the theory non-perturbatively. The classic Backlund transformations act to change the number of D-branes, or the number of units of flux. This rather beautiful connection reconnects the string theories to the underlying integrable structures in a way which suggests an intriguing and instructive geometrical language. Generalizations are discussed.
