Poisson resolutions
A resolution
Z ?
X of a Poisson variety
X? is
called
Poisson if every Poisson structure on
X?
lifts to a
Poisson structure on
Z. For symplectic varieties, we prove that Poisson
resolutions coincide with symplectic resolutions. It is shown that for a smooth
Poisson surface
S, the natural resolution
S [n?
] ?
S (n?
) is a Poisson resolution. Furthermore, if
??
KS ? is base-point-free, we prove that this is the unique
projective Poisson resolution for
S (n?
).
