Let G be a commutative, unipotent, perfect, connected group scheme over an algebraically closed field of characteristic p > 0 and let E be a biextension of G x G by the discrete group Qp/Zp . When E is skew-symmetric, V. Drinfeld defined a certain metric group A associated to E (when G is the perfectization of the additive group Ga , it is easy to compute this metric group - cf. Appendix A). In this dissertation, we prove a conjecture due to Drinfeld about the class of the metric group A in the Witt group (cf. Appendix B)
