Research

Sarti is the namesake of the Sarti surfaces (also called Sarti dodecics) a family of degree-12

nodal surface In algebraic geometry, a nodal surface is a surface in (usually complex) projective space whose only singularities are nodes. A major problem about them is to find the maximum number of nodes of a nodal surface of given degree. The following tabl ...

s with 600 nodes that she discovered in 1999 and published in 2001. One member of the family can be chosen so that 560 of the nodes have real rather than complex coordinates. The Sarti surface has a surface as one of its quotients, and some of Sarti's other publications include research on the symmetries of surfaces.

Personal life

Sarti has a twin sister, Cristina Sarti, who also did a Ph.D. in mathematics in Germany.
