Abstract
A classification of locally free sheaves \( \mathcal{E} \) of \( \mathcal{O} \)-modules which have a given retract gr\( \mathcal{E} \) in the terms of non-abelian 1-cohomology is given. In the case of \( \mathbb{C}{{\mathbb{P}}^{1|m }} \), m > 0, we show that the Birkhoff–Grothendieck Theorem does not hold true. We obtain a result similar to the Barth–Van de Ven–Tyurin Theorem for projective superspaces. Furthermore, a spectral sequence which connects the cohomology with values in a locally free sheaf \( \mathcal{E} \) to the cohomology with values in its retract gr\( \mathcal{E} \) is constructed.
