Abstract:
We investigate $s\ell_n$ conformal Toda theory with maximally symmetric boundaries, using classical and conformal bootstrap methods. We compare the results with the wellknown case of Liouville theory ($n=2$). For all values of $n\ge 2$, we find that there exist Dbranes of all possible dimensions $0\le d\le n1$. For $n\ge 3$ however, there appear infinite multiplicities in the boundary spectrum, in sharp contrast with the Liouville case.
