In this paper, we show that any nonlinear mixed *-Jordan-type higher derivation on unital *-algebras is an additive higher *-derivation. As applications, nonlinear mixed *-Jordan-type higher derivations on some classical unital *-algebras, such as prime *-algebras, von Neumann algebras of type I1, factor von Neumann algebras and standard operator algebras, are characterized, and some conclusions are extended.
Ren et al. (Wed,) studied this question.
