Abstract.
For a convex body \(\mathcal{B}\) in \(\mathbb{R}^3 \) which is invariant under rotations around one coordinate axis and has a smooth boundary of bounded nonzero curvature, the lattice point discrepancy \(P_\mathcal{B} (t)\) (number of integer points minus volume) of a linearly dilated copy \(\sqrt t \mathcal{B}\) is estimated from below. On the basis of a recent method of K. Soundararajan [16], an Ω-bound is obtained that improves upon all earlier results of this kind.
