Transitive Actions of Semigroups on semi-simple Lie Groups

We give necessary conditions for a action of subsemigroup to be transitive on homogeneous spaces. (With Luiz A. B. San Martin) |PDF|PS|DVI|

On the continuity of the Zadeh's Extension

We analyze the properties of the Fuzzy zadeh's extensions giving conditions for the continuity-1996. (with Laecio C. Barros and Rodney Bassanezi) |PDF|PS|DVI|

Remarks on deterministic orbits of Fuzzy Dynamical Systems

we prove some results concerning the solutions of a differential equations and the orbits of the fuzzy extensions of the vector fields-1996. (with Laecio C. Barros and Rodney Bassanezi) |PDF|PS|DVI|

Attractors and Asymptotic Stability for Fuzzy Dynamical Systems

Inthis work we study the asymptotic properties of Maps on fuzzy spaces which are extensions of continuous maps in R^n. The main results are in the section 4, and we give an illustrative example in the last section-1997. (with Laecio C. Barros and Rodney Bassanezi) |PDF|PS|DVI|

Asymptotic Smoothness of the Extension of Zadeh

Extending a map of R^n with compact attractor doesn't mean that the extension is asymptotically smooth. - 2001 (with Laecio C. Barros and Suzana Oliveira) |PDF|PS|DVI|
