Author's Comments: This represents part of my Ph.D. thesis.
Abstract: This paper provides some technical results
needed in "Formalism for Relative
GromovWitten Invariants." We study
linebundles on the moduli stacks of relative
stable and rubber maps that are used to
define relative GromovWitten invariants in
the sense of J. Li. Relations between these
linebundles yield degeneration formulae. In
addition we prove a technical result called
the Trivial Cylinders Theorem.
