How to Integrate over Grassmann Numbers in Quantum Field Theory? (Berezin Integral)

Показать описание
In this video, we will show you how to do integrals with Grassmann numbers. Grassmann numbers are an important concept in quantum field theory, where we use them to describe fermions. They are named after the German mathematician Hermann Grassmann. The special thing about Grassmann numbers is that they do not commute. For usual numbers, 4*3 is the same as 3*4, but for two Grassmann numbers theta_1 and theta_2, their product is not the same if we exchange them!

I love your explanations cause they resume pages and pages that take me hours to read lol thank you very much!

I can not emphasis on how much this topic confused me in SUSY, this is great for people to learn,
Great job !

Super thanks .
we would like to seen how they used also in supersymmetry .

Fantastic video, please make a video on something like complete electrodynamics in a nutshell. From maxwells equation to Electromagnetic field Tensor.

Excellent video! May I ask how did you take the notes? Are you using GoodNotes? Could you share colors/ thickness/pen settings in that case?

what about integrals of higher powers of grassman numbers (2, 3, 4, ... etc) would their integral be zero as well?
