Query: Horizons of Coalescing Black Holes on Eguchi-Hanson Space   Using the numerical method, we study dynamics of coalescing black holes on
the Eguchi-Hanson base space. Effects of a difference in spacetime topology on
the black hole dynamics is discussed. We analyze appearance and disappearance
process of marginal surfaces. In our calculation, the area of a coverall black
hole horizon at the creation time in the coalescing black holes solutions on
Eguchi-Hanson space is larger than that in the five-dimensional Kastor-Traschen
solutions. This fact suggests that the black hole production on the
Eguchi-Hanson space is easier than that on the flat space.
