摘要：
This paper shows that the classes of sufficient and minimal sufficient sigma-fields are closed under products. The results are used to construct several examples that throw some light on the study of the relationship between minimal sufficiency and invariance, a problem posed in Hall, Wijsman and Ghosh (1965).
