Partially defined cocycles and the Maslov index for a local ring
Annales de l'Institut Fourier, Volume 54 (2004) no. 4, p. 875-885
In this paper we study some aspects of the cohomology of groups and we construct a central extension of the symplectic group Sp n (A).
Dans cet article on étudie certains aspects liés à la cohomologie des groupes et on construit une extension centrale du groupe symplectique Sp n (A).
