19 p, 384.4 KB Positive neighborhoods of curves / Luza, M. Falla (Universidade Federal Fluminense. Institute of Mathematics and Statistics (IME)) ; Sad, Paulo (Institute of Pure and Applied Mathematics-IMPA (Rio de Janeiro, Brasil))
In this work we study when neighborhoods of curves in holomorphic surfaces with positive self-intersection number can be embedded in the projective plane.

11 p, 131.6 KB Embedded curves and foliations / Movasati, Hossein (Instituto de Matemática Pura e Aplicada (Rio de Janeiro, Brasil)) ; Sad, Paulo (Instituto de Matemática Pura e Aplicada (Rio de Janeiro, Brasil))
We prove the existence of regular foliations with a prescribed tangency divisor in neighborhoods of negatively embedded holomorphic curves; this is related to a linearization theorem due to Grauert. We give also examples of neighborhoods which can not be linearized.

19 p, 231.4 KB Singularités nilpotentes et intégrales premières / Meziani, R. ; Sad, Paulo
This paper presents a classification of plane dicritical nilpotent singularities, i. e. singularities which have nilpotent linear part and infinitely many separatrices. In particular the existence of meromorphic first integrals is discussed. [...]
