Sunset on Bologna from the math department

Sunset on Bologna from the math department.

Roberto Pagaria

Research associate in Mathematics

I am a researcher in algebraic topology at Bologna university. Several articles published in leading math journals. Advanced knowledge of Abelian arrangements, configuration spaces, matroids, representation theory, spectral sequences and quiver varieties, acquired during thesis works and research activities.

Software developed:

Giovanni Paolini and I have developed "arithmat": a SageMath package to have fun with arithmetic matroids and integer matrices. It can be download from GitHub or PyPI.
