 Hjalte Frellesvig 博士学术报告

Title: Feynman Integrals, Intersection Theory, and other Ideas

Speaker: Hjalte Frellesvig

Affiliation: Niels Bohr Institute, Denmark (丹麦尼尔斯·玻尔研究所)

Time: 16:00-17:00, Tuesday, 21st May, 2024 (UTC+8, Beijing Time)

Venue: Zoom Meeting (ID: 385 442 0225; Passcode: yauc)

Inviter: Zhengwen Liu (刘正文)



Feynman integrals are the main mathematical building block of high precision contributions to scattering amplitudes in quantum field theories.

In this talk I will discuss my work on these fascinating objects, such as their connection to the mathematical field of intersection theory, the geometric structures that may appear as integration surfaces, and the integrals that appear in expressions for Higgs production in the Standard Model.



Dr. Hjalte Frellesvig has his PhD from the Niels Bohr Institute, and has done postdocs in Greece, Germany, and Italy before returning to NBI. His main field of research is scattering amplitudes in particle physics, with a focus on Feynman integrals and their mathematical properties. This includes work on the use of the mathematical disciplines of intersection theory and 'symbol' algebra for simplifying and systematizing the manipulation and evaluation of Feynman integrals and associated special functions. He also works on particle scattering phenomenology including a project on the production of the Higgs boson, and one on electro-weak corrections to the production of the Z and W bosons.


The seminar will be broadcasted online by Zoom.

Interested people are free to join, without registration in advance.
