Abstract: In this article, we investigate various properties of the pure virtual braidgroup PV 3. From its canonical presentation, we obtain a free productdecomposition of PV 3. As a consequence, we show that PV 3 is residuallytorsion free nilpotent, which implies that the set of finite type invariants inthe sense of Goussarov-Polyak-Viro is complete for virtual pure braids withthree strands. Moreover we prove that the presentation of PV 3 is aspherical.Finally we determine the cohomology ring and the associated graded Lie algebraof PV 3.
