**DELLACHERIE, Claude**

Un crible généralisé (Descriptive set theory)

Given a Borel set $A$ in the product $E\times F$ of two compact metric sets, the set of all $x\in E$ such that the section $A(x)\subset Y$ is of second category is analytic

Comment: The authour discovered later that the main result is in fact due to Novikov: two references are given in 1252

Keywords: Analytic sets

Nature: Original
