There's a question that asks me to show that there exists a unique linear transformation
from: [tex]f\otimes g: V_1\otimes W_1\rightarrow V_2\otimes W_2[/tex]
where f and g are linear transformations f:V1->V2, g:W1->W2
that satisfies: [tex](f\otimes g)(u\otimes v)=f(u)\otimes g(v)[/tex]
well I think that what I need to show is only that
it's linear by first componenet and second componenet which I did.
well if that's it for linear (including multplication by a scalar), then now I need to show uniqueness, well I guess this depends on f and g is it not?
well it's unique by our choice of f and g, with other functions we would have a different linear transformation.
What do I miss here?
thanks in advance.
