The following results are proved: 1) If dim(M) = 2 and S is globally semianalytic, then every connected component of S is again globally semianalytic. 2) S is globally semianalytic, if and only if its boundary Bd(S) is globally semianalytic.journal articlehttp://gdz.sub.uni-goettingen.de/no_cache/dms/load/toc/?IDDOC=238618metadata only access512.7globally semianalytic setsGeometria algebraica1201.01 Geometría Algebraica
