Abstract Note  We summarize the situation regarding nonpolynomial Lagrangians: I should make the qualification that an enor?? mous amount of verification is needed before the problems of renormalizability are all sorted out, but one may ten?? tatively state: 1) All matrix elements are finite for theories where the Dyson index D is less than two. 2) For the cases when D=2 or 3, counterterms have been explicitly written which absorb all infinities and the theories are renormalizable. 3) Mixed theories of polynomial and nonpolynomial fields appear to be renormalizable provided the Dyson in?? dices separately and jointly fulfill renormalizability criteria. We believe that weak interactions, chiral La?? grangians and YangMills theory fall into this class though detailed proofs have not yet been constructed. 4) It seems likely that to each order in the major coupling (and to all orders in the minor coupling}the S?? matrix elements, as computed by methods outlined, satisfy the necessary unitarity and analyticity requirements
