Abstract:
In this paper, we analyze solutions of the open Toda system and establish an optimal Moser-Trudinger type inequality for this system. Let be a closed surface with area 1 and
the Cartan matrix for SU(N+1), i.e.,
We show that
has a lower bound in if and only if
has a lower bound in if and only if As a direct consequence, if
for
,
has a minimizer u which satisfies
