AB - <p style="text-align: justify;">We study substructuring preconditioners for the linear
system arising from the discretization of parabolic problems when the
mortar method is applied. By using a suitable non standard norm
equivalence we build an efficient edge block preconditioner and we prove
a polylogarithmic bound for the condition number of the preconditioned
matrix.</p>
