Regular products of single-hook characters of the unitary group are defined. Their expansion in terms of irreducible characters is discussed and illustrated, along with the inverse of this expansion for all characters labelled by partitions of n with n=5 and n=9. It is shown that these regular products form an integral basis for the vector space of homogeneous functions.
