Abstract: Let (A, m) be a Noetherian local ring with infinite residue field and let I bean ideal in A and let F(I) = circle plus(n >= 0) I(n)/mI(n) be the fiber cone of I. We prove certain relations among the Hilbert coefficients f(0)(1), f(1)(1), f(2)(I) of F(I) when the a-invariant of the associated graded ring G(1) is negative.
