5. Factor out the unit-norm basis (and operator symmetry) tests once
all of the algebras pass.
-6. Implement spectral projector decomposition for EJA operators
- using jordan_form() or eigenmatrix_right(). I suppose we can
- ignore the problem of base rings for now and just let it crash
- if we're not using AA as our base field.
-
-7. Do we really need to orthonormalize the basis in a subalgebra?
- So long as we can decompose the operator (which is invariant
- under changes of basis), who cares?
+6. Can we make the minimal and characteristic polynomial tests work
+ for trivial algebras, too? Then we wouldn't need the "nontrivial"
+ argument to random_eja().
