Determine A. i 4: Let V be a real vector space. A complex structure on V is a real linear mapping J : V → V satisfying J 2 = −Id where Id is the identity mapping. Prove that under the addition operation of V and scalar multiplication deﬁned by (a + bi)x = ax + bJ (x) for all a + bi ∈ C and x ∈ V , that V becomes a complex vector space. 1 ...
