Query: Hermitian realizations of kappa-Minkowski spacetime   General realizations, star products and plane waves for kappa-Minkowski
spacetime are considered. Systematic construction of general hermitian
realization is presented, with special emphasis on noncommutative plane waves
and hermitian star product. Few examples are elaborated and possible physical
applications are mentioned.
