While there is now a robust theory for integral equations of computational electromagnetics, the computational solution, including fast discretisation and preconditioning remains a challenging topic, both in the low-frequency and high-frequency limit. In this minisymposium we bring together leading experts in this field to discuss open topics, spanning fast discretisation methods, preconditioning, numerical stability, integral equations on rough domains, and complex domain decomposition.
