Abstract
We construct general matter couplings of N=1 four-dimensional suèergravity for theories with curavture-squared terms, suggested by D=10 anomaly-free supergravity and superstrings. The scalar potential induced by the supersymmetric completion of the Euler characteristic is derived and its positivity properties dicussed. Some implications for the nonpolynomial structure of ten-dimensional supergravity are drawnFile in questo prodotto:
