I am currently a Phd graduate at the University of Florence. I completed a thesis on "Grid homology in lens spaces" under the supervision of Prof. Paolo Lisca.

I am interested in low dimensional topology, with a focus on knot theory and its many
connections with the topology of 3 and 4 dimensional manifolds.
My current work revolves around Khovanov and Knot Floer homologies,
especially Grid Homology in lens spaces.

Programs

Here you can find some (hopefully!) useful programs I have been writing in during my Phd.

Click on the images to get redirected to a Sage script!

Grid homology calculator for knots in lens spaces

This program lets you draw grid diagrams

This program computes the Alexander polynomial of a 2-bridge knot or link,
and tells you if it is (smoothly) slice.

This program computes the number of homeomorphism classes of the lens spaces L(p,q) for fixed p.


This program computes the correction terms for lens spaces

This program computes the Alexander polynomial of a grid diagram in the 3-sphere




Soon other programs will be added!

All the programs are released under a GNU General Public Licence.

Practically this means that you can use or modify them as you please, according to the copyleft model. Let me know if you encountered problems using them, or if you have suggestions!

About me

I am one of the organizers of the "Baby geometri" seminars at the University of Pisa.

I enjoy juggling any kind of objects, and thinking at all the math behind it.

I am a big fan of :
