Query: More on a dessin on the base: Kodaira exceptional fibers and mutually
  (non-)local branes   A "dessin d'enfant" is a graph embedded on a two-dimensional oriented surface
named by Grothendieck. Recently we have developed a new way to keep track of
non-localness among 7-branes in F-theory on an elliptic fibration over $P^1$ by
drawing a triangulated "dessin" on the base. To further demonstrate the
usefulness of this method, we provide three examples of its use. We first
consider a deformation of the $I_0^*$ Kodaira fiber. With a dessin, we can
immediately find out which pairs of 7-branes are (non-)local and compute their
monodromies. We next identify the paths of string(-junction)s on the dessin by
solving the mass geodesic equation. By numerically computing their total
masses, we find that the Hanany-Witten effect has not occurred in this example.
Finally, we consider the orientifold limit in the spectral cover/Higgs bundle
approach. We observe the characteristic configuration presenting the cluster
sub-structure of an O-plane found previously.
