He was an invited speaker in 2003 in Lisbon at the 14th ICMP (Construction of a 2-dimensional Fermi Liquid, from work with Knörrer and Trubowitz).
Feldman in 1997 in Brisbane at the 12th ICMP delivered a plenary address (Renormalization of the Fermi surface, from work with Salmhofer and Trubowitz).
