Quadratic Jordan superpairs covered by grids
In this paper we lay the foundation for a theory of Jordan superpairs
defined over (super)commutative superrings. The framework we are proposing
has two novelties: we allow scalars of even and odd parity and we do not
assume that 2 is invertible in our base superring. To demonstrate that it
is possible to work in this generality we classify Jordan superpairs covered
by a grid.
This is a revised version (1 May 2003) of a paper posted originally on 1
