Abstract: We study several algebraic properties of dual covariance and weighted dual covariance sets in rings with involution and C*‐algebras. Moreover, we show that the weighted dual covariance set, seen as a multivalued map, has some kind of continuity. Also, we prove weighed dual covariance set invariant under the bijection multiplicative *‐functions.
