Nobel lecture: from weak interactions to gravitation

Veltman M.J.G.

This lecture is about my contribution to the proof of renormalizability of gauge theories. There is of course no perfectly clear separation between my contributions and those of my co-laureate ‘t Hooft, but I will limit myself to some brief comments on those publications that carry only his name. An extensive review on the subject including more detailed references to contemporary work can be found elsewhere (Veltman, 1992a).
