The mathematical field of intersection theory has provided an important new perspective on Feynman integrals and the relations between them. With this approach it is possible to derive such relations with a direct projection, providing a promising alternative to the IBP-based approach. These proceedings will discuss a new development based on relative cohomology which is a perfect fit for the mathematical structure of Feynman integrals and which can further accelerate the intersection-based approach to master integral decomposition.
