摘要：
The predictive power of perturbative Quantum Field Theory relies on the computation of Feynman integrals (FIs). By exploiting basic analytic structures and especially singularities, we can directly solve FIs by an ansatz together with corresponding constraint conditions in certain cases, which turns the calculation into a linear algebra problem. This approach is known as the bootstrap method. In this talk, I will discuss how to use this method along with differential equations to solve Feynman integrals both in N=4 super-Yang-Mills theory and the Standard Model, with an emphasis on the singularity information.
