Description
Feynman integrals generally admit non-local symmetries that lead to partial differential equations that strongly constrain the functional form that the integrals can take. In this talk I will review these symmetries and study the constraints they impose in the simple setup of Feynman integrals in one or two spacetime dimensions. In particular I will describe a bootstrap method allowing the explicit computation of many examples including families at any number of points or loops. Furthermore, I will discuss some surprising simplicity in the final results hinting at an even simpler bootstrap procedure that should also generalize to higher dimensions.
