(Ethno)mathematics as discourse
(2015-01-01)
Interpreting mathematics as a discourse includes three claims: that there are forms of mathematics-reality transitions, that mathematics includes actions, and that mathematics includes a political dimension. Through a ...
Teaching and learning data structures supported by computers: An experiment using CADILAG tool
(2012-11-19)
This paper aims to present the use of a learning object (CADILAG), developed to facilitate understanding data structure operations by using visual presentations and animations. The CADILAG allows visualizing the behavior ...

From localized spots to the formation of invaginated labyrinthine structures in a Swift-Hohenberg model
(Elsevier, 2015)
The stability of a circular localized spot with respect to azimuthal perturbations is studied in a prototype variational model, namely, a Swift-Hohenberg type equation. The conditions under which the circular shape of the ...
Formation of wakes by chiral conducting cosmic strings
(World Scientific Publ Co Pte Ltd, 2004-10-20)
Chiral cosmic strings are naturally produced at the end of D-term inflation and they present very interesting cosmological consequences. In this work, we investigate the formation and evolution of wakes by a chiral string. ...
