Examples of Calabi-Yau 3-folds of with
Marie-Am\' elie Bertin
We give some examples of Calabi-Yau 3-folds with , defined over and constructed as 4-codimensional subvarieties of via commutative algebra methods.…
On singular varieties having an extremal secant line
Marie-Amélie Bertin
We correct a mistake in an earlier paper and give a complete classification of singular varieties having an extremal secant line.
On trisecant lines to White surfaces
Marie-Amelie Bertin
In this work we show that the only White surface in the projective 5-space having an excess of trisecant lines is the polygonal surface constructed by C. Segre. The proof follows t…
On the regularity of varieties having an extremal secant line
Marie-Amélie Bertin
The Castelnuovo-Mumford regularity of varieties of degree r and dimension n in the r-dimensional projective space that have an extremal secant line, is at least d-r+n+1. We classif…
