| Abstract |
We compute the Poisson cohomology of a scalar Poisson bracket of Dubrovin–Novikov type with D independent variables. We find that the second and third cohomology groups are generically non-vanishing in D>1. Hence, in contrast with the D=1 case, the deformation theory in the multivariable case is non-trivial.
