概要
The notion of liftable vector fields was introduced by V. I. Arnol'd
for studying of bifurcations of wave front singularities. To investigate
generators for the module of liftable vector fields defined for a
multigerm, bijectivity of a higher version of the reduced
Kodaira-Spencer-Mather map of the mutigerm is important. We
investigate a higher version of the reduced Kodaira-Spencer-Mather map
for a multicusp and construct generators for the associated module of
liftable vector fields.
