Abstract :
In this paper, we first give a characterization of sub-topical functions
with respect to their lower level sets and epigraph. Next,
by using two different classes of elementary functions, we present
a characterization of sub-topical functions with respect to their
polar functions, and investigate the relation between polar functions
and support sets of this class of functions. Finally, we
obtain more results on the polar of sub-topical functions.
