We make this intuition formal in the context of the non-deterministic λ-calculus by introducing a finiteness structure on resource terms, which is such that a λ-term is strongly normalizing iff the support of its Taylor expansion is finitary. An application of our result is the existence of a normal form for the Taylor expansion of any strongly normalizable non-deterministic λ-term. %G English %2 https://hal.science/hal-01292923/document %2 https://hal.science/hal-01292923/file/main.pdf %L hal-01292923 %U https://hal.science/hal-01292923 %~ UNIV-PARIS7 %~ CNRS %~ UNIV-AMU %~ EC-MARSEILLE %~ I2M %~ I2M-2014- %~ USPC %~ UNIV-PARIS %~ UP-SCIENCES %~ IRIF
