Scattering amplitudes, integrability via computational algebraic geometry: A Singular Approach.

Referent: Prof. Dr. Yang Zhang (ETH Zürich)

Abstrakt:

The current development of theoretical physics, especially in the fields of scattering amplitudes and integrability, involves a lot of novel approaches from computational algebraic geometry. We aim at solving several bott- leneck problems in modern physics, using algebraic geometry tools like Groebner basis, syzygies, resultant and also D-module tools like polyno- mial annihilators. I will present reducing LHC-related complicated Feyn- man integrals with syzygies and solving Bethe Ansatz equations with Gro- ebner basis/resultant, as explicit examples. The usage of Singular for the- se frontier physics problems will be discussed.
