RT Journal Article T1 Connected components of global semianalytic subsets of 2-dimensional analytic manifolds. A1 Castilla, A. A1 Andradas Heranz, Carlos AB Let M be a connected paracompact real analytic manifold and S a semi-analytic subset.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.
