The variant of Goedel’s system T of primitive recursive functionals of finite type which is based on typed lambda-calculus can be seen as a paradigm for higher order rewrite systems.

In an article joint with A.Weiermann (LMCS 2012) T was analyzed using an assignment technique extending Howard’s original assignment from 1970. In my talk I am going to explain this technique under two aspects: the non-unique assignment needed in the argument, which goes back to Howard’s original treatment, and Weiermann’s collapsing technique, which allowed for a derivation lengths classification of T.
