Startpoints and $(\alpha,\gamma)$-Contractions in Quasi-Pseudometric   Spaces
  We introduce the concept of $\it{ startpoint}$ and $\it{endpoint}$ for multivalued maps defined on a quasi-pseudometric space. We investigate the relation between these new concepts and the existence of fixed points for these set valued maps.
