The Influence of Black Hole Binarity on Tidal Disruption Events
  Mergers are fundamental to the standard paradigm of galaxy evolution, and
provide a natural formation mechanism for supermassive black hole binaries. The
formation process of such a binary can have a direct impact on the rate at
which stars are tidally disrupted by one or the other black hole, and the
luminous signature of the tidal disruption itself can have distinct imprints of
a binary companion. In this chapter we review our current understanding of the
influence of black hole binarity on the properties of tidal disruption events.
We discuss the rates of tidal disruption by supermassive black hole binaries,
the impact of a second black hole on the fallback of debris and the formation
of an accretion flow, and the prospects for detection of tidal disruption
events by supermassive black hole binaries.
