SUMMARY

The dual of a finite-dimensional vector space V, expressed as the direct sum V = Z ⊕ W, can be represented as the direct sum of the duals of Z and W. This conclusion is based on the properties of dual spaces in linear algebra. Specifically, if V is decomposed into Z and W, then the dual space V* is equivalent to Z* ⊕ W*. This relationship is fundamental in understanding the structure of dual spaces and their applications in various mathematical contexts.

Hi, All:

Let V be a finite-dimensional space, which can be decomposed as:

V=Z(+)W . How can we express the dual of V in terms of the duals of

Z, W?

I think this has to see with tensor products, but I'm kind of rusty here.

Any ideas, please?

The dual of the direct sum is the direct sum of the duals.
