Symmetric Kronecker products and semiclassical wave packets
(40K, latex)

ABSTRACT.  We investigate the iterated Kronecker product of a square matrix 
with itself and prove an invariance property for symmetric subspaces. 
This motivates the definition of an iterated symmetric Kronecker product 
and the derivation of an explicit formula for its action on vectors. 
We apply our result for describing a linear change in the matrix 
parametrization of semiclassical wave packets.
