*Abstract:
Given a real analytic set X in a complex manifold and a positive integer d, denote by A(X,d) the set of points p in X for which there exists a germ at p of a complex analytic set of dimension at least d contained in the germ of X at p. It is proved that the A(X,d) are closed semianalytic subsets of X. If, moreover, X is real algebraic, then the A(X,d) are semialgebraic.
