We establish some explicit expressions for norm-wise, mixed and componentwise
condition numbers for the weighted Moore-Penrose inverse of a matrix $A⊗B$ and
more general matrix function compositions involving Kronecker products. The condition
number for the weighted least squares problem (WLS) involving a Kronecker
product is also discussed.
