| ``invariants of the tensor product''
by mcintosh on 2003-10-04 19:51:25 |
|
| The entry for "Kronecker Product" or alternatively "Tensor Product"
shows formulas for the trace, rank, and determinant of the product
in terms of those for its factors.
Are there corresponding formulas for the other invariants, and in
particular, can the characteristic equation of the product be
related to the characteristic equations of its factors?
At worst, I suppose they could be deduced by knowing all the roots.
