Abstract
Let be a group acting by homeomorphisms on a Hausdorff compact space . We constructed a new space that blows up equivariantly the bounded parabolic points of . This means, roughly speaking, that acts by homeomorphisms on and there exists a continuous equivariant map such that for every non bounded parabolic point , . We use such construction to characterize topologically some spaces that acts with the convergence property and to construct new convergence actions of from old ones. As one of the applications, if is a group and is a bounded parabolic point of the space of ends of , then the stabilizer of is one-ended.
