The derivation of linear relations between Feynman integrals is a computationally extremely heavy task when done with the traditional method based on integration-by-parts identities. Using insights from the mathematical field of intersection theory, I will describe a method to derive such linear relations directly from projections in the "vector space of Feynman integrals", and I will show a number of examples.
