I'm working on complex dynamical systems, more specifically on the local/global aspect of singular holomorphic foliations in the complex plane.
Update 23/06/11: I was believing deeply in what SE had to offer. These days are gone, the management and shareholders have killed everything: the spirit of the network and its honor. I've revoked all my SE accounts, only keeping MO active since it is not part of the network. As a community I believe we must leave the SE ship and its hostile owners.
