Resolved Photon Contributions to Leptoquark Production in $e^{+}{e}^{-}$ and $e\gamma$ Collision

We calculate the resolved photon contribution to leptoquark production at $e\gamma$ colliders for the center of mass energies $\sqrt{s}=500$~GeV and 1~TeV. We also calculate the resolved photon contribution to leptoquark production at $e^{+}{e}^{-}$ colliders for the center of mass energies $\sqrt{s} = 1$~and~2~TeV. In both cases we find that these contributions are considerably larger than the standard contributions considered in the literature.
