In this Note we study certain natural subsets of the cohomological stratification of the moduli spaces of rank \( 2 \) vector bundles on an algebraic surface. In the last section we consider the following problem: take a bundle \( E \) given by an extension, how can one recognize that \( E \) is a certain given bundle? The most interesting case considered here is the case \( E = T P^{3} (t) \) since it applies to the study of codimension \( 1 \) meromorphic foliations with singularities on \( P^{3} \).
