%0 Journal Article %T Examples of a complex hyperpolar action without singular orbit %A Koike %A Naoyuki %J Cubo (Temuco) %D 2010 %I Scientific Electronic Library Online %R 10.4067/S0719-06462010000200009 %X the notion of a complex hyperpolar action on a symmetric space of non-compact type has recently been introduced as a counterpart to the hyperpolar action on a symmetric space of compact type. as examples of a complex hyperpolar action, we have hermann type actions, which admit a totally geodesic singular orbit (or a fixed point) except for one example. all principal orbits of hermann type actions are curvature-adapted and proper complex equifocal. in this paper, we give some examples of a complex hyperpolar action without singular orbit as solvable group free actions and find complex hyperpolar actions all of whose orbits are non-curvature-adapted or non-proper complex equifocal among the examples. also, we show that some of the examples possess the only minimal orbit. %K symmetric space %K complex hyperpolar action %K complex equifocal submanifold. %U http://www.scielo.cl/scielo.php?script=sci_abstract&pid=S0719-06462010000200009&lng=en&nrm=iso&tlng=en
