Derived automorphism groups of K3 surfaces of Picard rank
We give a complete description of the group of exact autoequivalences of the bounded derived category of coherent sheaves on a K3 surface of Picard rank . We do this by proving that a distinguished connected component of the space of stability conditions is preserved by all autoequivalences and is contractible.
