Abstract
Conformal properties of the topological gravitational terms in , and are discussed. It is shown that in the last two cases the integrands of these terms, when being settled into the dimension and multiplied by a scalar, become conformal invariant. Furthermore we present a simple covariant derivation of the Paneitz operator in and formulate two general conjectures concerning the conformal properties of topological structures in even dimensions.
