To get started with this blank [[TiddlyWiki]], you'll need to modify the following tiddlers:
* [[SiteTitle]] & [[SiteSubtitle]]: The title and subtitle of the site, as shown above (after saving, they will also appear in the browser title bar)
* [[MainMenu]]: The menu (usually on the left)
* [[DefaultTiddlers]]: Contains the names of the tiddlers that you want to appear when the TiddlyWiki is opened
You'll also need to enter your username for signing your edits: <<option txtUserName>>
<link rel='alternate' type='application/rss+xml' title='RSS' href='index.xml' />
These [[InterfaceOptions]] for customising [[TiddlyWiki]] are saved in your browser

Your username for signing your edits. Write it as a [[WikiWord]] (eg [[JoeBloggs]])

I am a Full  Professor at the [[Department of Mathematics|]], [[ICMC-USP|]], at the USP campus at [[São Carlos|,-47.683411&sspn=1.716186,2.436218&ie=UTF8&hq=&hnear=S%C3%A3o+Carlos+-+S%C3%A3o+Paulo,+Brazil&ll=-21.207459,-46.318359&spn=53.616966,77.958984&t=h&z=4]]. My main interest on research is the study dynamical systems, and in particular one-dimensional dynamical systems, renormalization  and ergodic theory. I did my  Ph. D. at [[IMPA|]] (2001), under the supervision of [[Welington de Melo|]].

I gave a talk in  the conference  [[Geometric and Algebraic Structures in Mathematics|]]  at Stony Brook, May 25-June 4, 2011, a Conference to celebrate Dennis Sullivan’s 70th birthday.   The talk was about my current project on  renormalization for multimodal maps. The [[video|]] and  [[slides|]] are available in the website of the conference.  All the talks were recorded and you can see them [[here|]].
