Abstract

We prove that a pair of Feigin-Odesskii Poisson brackets on P4{\mathbb P}^4 associated with elliptic curves given as linear sections of the Grassmannian G(2,5)G(2,5) are compatible if and only if this pair of elliptic curves is contained in a del Pezzo surface obtained as a linear section of G(2,5)G(2,5).
