Extensões de Hopf-Ore e a décima conjectura de Kaplansky
(Universidade Federal de Santa Maria, 2019-06-28)
In this work we will treat, in particular, of the Hopf algebras and Hopf-Ore extensions.
One of ours main goals is to prove a theorem that characterizes when a Hopf algebra R
is a extension of Hopf-Ore of a Hopf algebra ...
Ray tracing em tempo real usando hierarchical scene signed distance fields
(Universidade Federal de Santa Maria, 2019-03-25)
Ray tracing is an important technique for obtaining photo-realistic images. The basic algorithm
is well known and consists of tracing rays from a synthetic camera position by
calculating the color of objects colliding ...
