Find a basis of U , and prove that it is a basis using the deﬁnitions. 3. The deﬁnition of a vector space makes complete sense if we let the scalars ( F ) be the integers instead of the reals or the complexes (though you wouldn’t call that a vector space).

Unformatted text preview: Check that all the axioms are satisﬁed if we let V be the example from class: V = { , v } , and addition is deﬁned by + = , + v = v , v + = v , v + v = and multiplication by the integers by a · = , a · v = 0 if a is even, v is a is odd. You’ll have to do that by cases. For instance, additive associativity has 8 possibilities. 1...
