Example of a foliation for Ueda type one
Paulo Sad
We give an example of a regular 2-dimensional foliation along a curve of genus 3 whose Ueda type is one and normal bundle is of order two
Regular Foliations and Trace Divisors
Paulo Sad
An example is given of a divisor of a curve which is not a trace divisor of a foliation.
Positive neighborhoods of curves
M. Falla Luza, P. Sad
In this work we study neighborhoods of curves in surfaces with positive self-intersection that can be embeeded as a germ of neighborhood of a curve on the projective plane.
Positive neighborhoods of rational curves
M. Falla Luza, P. Sad
We study neighborhoods of rational curves in surfaces with self-intersection number 1 that can be linearised.
Extension of germs of holomorphic foliations
Gabriel Calsamiglia, Paulo Sad
We consider the problem of extending germs of plane holomorphic foliations to foliations of compact surfaces. We show that the germs that become regular after a single blow up and…
Embedded Curves and Foliations
Hossein Movasati, Paulo Sad
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 theor…
