1. Teoria de Nielsen de raízes e teoria do grau de Hopf / Nielsen Root Theory and Hopf Degree Theory
In this work, we are going to see that the concept of Nilsen Root Number can be extended to maps between not necessarily orientable nor compact manifolds, with or without boundary.

2. Bialgebra cohomology, deformations, and quantum groups.
We introduce cohomology and deformation theories for a bialgebra A (over a commutative unital ring k) such that the second cohomology group is the space of infinitesimal deformations. Our theory gives a natural identification between the underlying k-modules of the original and the deformed bialgebra. Certain explicit deformation formulas are given for the c
