Reclassifying Feynman integrals as special functions

Although Feynman integrals in general cannot be expressed as well-studied special functions, they can be calculated systematically and efficiently using the $\mathtt{\text{AMFlow}}$ method in combination with differential equations in the kinematic space. Therefore, it is constructive to define Feynman integrals as a new class of special functions (or transcedental numbers if there is no kinematic variable). Several crucial avenues for further exploration in this direction are outlined.
