Description

In this talk we describe the key points that made feasible the high-precision calculation of the 4-loop electron g-2: i.b.p. identities, high-precision solution of difference or differential equations and the analytical fit with PSLQ. We will take a first look to the 5-loop calculation, and discuss how the 4-loop approach could be extended to 5 loop.
