This paper investigates the properties of the Poisson bracket of polynomials in n variables and proves that there are strict constraints on the homogeneous components of the polynomials when the degree of the Poisson bracket is small enough. It also establishes a relationship between the homogeneous components of a polynomial F with degrees deg F ???1 and deg F ???2, and presents some results on the divisibility of the homogeneous component of degree deg F ??? 1. Furthermore, a modification of a conjecture regarding the estimation of the degree of the Poisson bracket of two polynomials is proposed.
Let F, G ??? C[x1, . . . , xn] be polynomials in n variables x1, . . . , xn over C. We prove that if the degree of the Poisson bracket [F, G] is small enough then there are strict constraints for homogeneous components of these polynomials. We also prove that there is a relationship between the homogeneous components of the polynomial F of degrees deg F ???1 and deg F ???2 as well some results about divisibility of the homogeneous component of degree deg F ??? 1. Moreover we propose a modification of the conjecture of Yu regarding the estimation of the degree of the Poisson bracket of two polynomials.
