Finitely curved orbits of complex polynomial vector fields Anais da ABC (AABC)
Mafra,Albetã C..
This note is about the geometry of holomorphic foliations. Let X be a polynomial vector field with isolated singularities on C². We announce some results regarding two problems: 1. Given a finitely curved orbit L of X, under which conditions is L algebraic? 2. If X has some non-algebraic finitely curved orbit L what is the classification of X? Problem 1 is related to the following question: Let C <FONT FACE=Symbol>Ì</FONT> C² be a holomorphic curve which has finite total Gaussian curvature. IsC contained in an algebraic curve?

The Gauss Map of Complete Minimal Surfaces with Finite Total Curvature Anais da ABC (AABC)
HINOJOSA,PEDRO A.; SILVA,GILVANEIDE N..
In this paper we are concerned with the image of the normal Gauss map of a minimal surface immersed in ℝ3 with finite total curvature. We give a different proof of the following theorem of R. Osserman:The normal Gauss map of a minimal surface immersed inℝ3with finite total curvature, which is not a plane, omits at most three points of&#55349;&#56650;2Moreover, under an additional hypothesis on the type of ends, we prove that this number is exactly 2.
