Abstract:
In this paper, it is shown that a sortable ideal
$I$
is Freiman
if and only if its sorted graph is chordal.
This characterization is used to give a
complete
classification of Freiman principal Borel ideals and of Freiman Veronese-type ideals
with constant bound.
Keywords:
Freiman ideal, sorted ideal, principal Borel ideal, Veronese-type ideals with constant
bound.
