Abstract
We prove that the space of symplectic embeddings of standard balls into the standard complex projective plane is homotopy equivalent to the configuration space of points in , provided that the sum of the capacities of the balls is strictly less than the symplectic area of a line. Moreover, our techniques suggest that, for , there are infinitely many homotopy types of spaces of symplectic ball embeddings, depending on the capacities of the balls.
