Splitting of Singular Fibers in Certain Holomorphic Fibrations
We will consider splitting of certain singular fibers. The singular fibers dealt with in this paper are the singular fibers in certain holomorphic fibration of genus $g$ whose total space is diffeomorphic to $\cp2 \# (4 g + 5) \bcp$. We study how these singular fibers split into Lefschetz type singular fibers. We also study the monodromies about the new Lefschetz type singular fibers obtained by splitting.
