Query: A note on Quadratic and Hermitian Groups   In this article we deduce an analogue of Quillen's Local-Global Principle for
the elementary subgroup of the general quadratic group and the hermitian group.
We show that the unstable K_1-groups of the hermitian groups are nilpotent by
abelian. This generalizes earlier results of A. Bak, R. Hazrat, N. Vavilov and
etal..
