Abstract

Let f:XAf: X \rightarrow A be an abelian cover from a complex algebraic variety with quotient singularities to an abelian variety. We show that ff^* induces an isomorphism between the rational cohomology rings H(A,Q)H^\bullet(A, \mathbb{Q}) and H(X,Q)H^\bullet(X, \mathbb{Q}) if and only if ff^* induces an isomorphism between the Chow rings with rational coefficients CH(A)Q\mathrm{CH}^\bullet(A)_{\mathbb{Q}} and CH(X)Q\mathrm{CH}^\bullet(X)_{\mathbb{Q}}.
