Similarly, maximal compact subgroups of noncompact exceptional Lie groups of types $E_{6(-26)}$ and $E_{6(6)}$ act on exceptional Jordan algebras $¥Im^{1}$ and $¥Im'$ , respectively. We give the orbit spaces of the Jordan algebras under these actions, respectively. Moreover, we give the orbit types of a maximal compact subgroup of $E_{6(6)}$ in $¥Im'$.}, pages = {11--21}, title = {ORBIT SPACES OF JORDAN ALGEBRAS WITH RESPECT TO EXCEPTIONAL LIE GROUPS AND THEIR ORBIT TYPES}, volume = {50}, year = {2003} }
