On a Conjecture Concerning a Theorem of Cramér and Wold

Guenther Walther

Journal of Multivariate Analysis, 1997, vol. 63, issue 2, 313-319

Abstract: A conjecture concerning the Cramér-Wold device is answered in the negative by giving a Fourier-free, probabilistic proof using only elementary techniques. It is also shown how a geometric idea allows one to interpret the Cramér-Wold device as a special case of a more general concept.
