Strong Normalizability as a Finiteness Structure via the Taylor   Expansion of {\lambda}-terms
  In the folklore of linear logic, a common intuition is that the structure of finiteness spaces, introduced by Ehrhard, semantically reflects the strong normalization property of cut-elimination. We make this intuition formal in the context of the non-deterministic {\lambda}-calculus by introducing a finiteness structure on resource terms, which is such that a {\lambda}-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 {\lambda}-term.
