We solve the following problem: to describe in geometric terms all
differential operators of the second order with a given principal symbol.
Initially the operators act on scalar functions. Operator pencils acting on
densities of arbitrary weights appear naturally in the course of study. We show
that for the algebra of densities it is possible to establish a one-to-one
correspondence between operators and brackets generated by them. Everything is
applicable to supermanifolds as well as to usual manifolds. In the super case
the problem is closely connected with the geometry of the Batalin--Vilkovisky
formalism in quantum field theory, namely the description of the generating
operators for an odd bracket. We give a complete answer. This text is a concise
outline of the main results. A detailed exposition is in
\texttt{arXiv:math.DG/0212311}.
