Abstract: The minimal Gröbner-Shirshov bases of the positive part $ B_n^+$ of a simple finite-dimensional Lie algebra $ B_n$ over an arbitrary field of characteristic 0 are calculated, for the generators associated with simple roots and for an arbitrary ordering of these generators (i.e., an arbitrary basis of the $ n!$ Gröbner-Shirshov bases is chosen and studied). This is a completely new class of problems; until now, this program was carried out only for the Lie algebra $ A_n^+$. The minimal Gröbner-Shirshov basis of the Lie algebra $ B_n^+$ was calculated earlier by Bokut and Klein, but this was done for only one ordering of generators.
