## Abstract The notion of Q7โbranes and Qโinstantons is introduced. These are oneโhalf BPS solutions of the type IIB supergravity theory characterized by a set of three parameters p,q,r such that r^2>4pq. The numbers p,q,r parameterize the electric and magnetic couplings of, respectively, the Q7โbr
