Question
Exercise 1.2.11 Show that conjugation respects multiplication, i.e.,
Notice that the function
C₁ x C₂ = C1 x C₂.
(1.47)
CIT
(1.48)
given by conjugation is bijective, i.e., is one-to-one and onto. Indeed, two different complex numbers are never sent to the same number by conjugation. Moreover, every number is the complex conjugate of some number. A function from a field to a field that is bijective and that respects
addition and multiplication is known as a field isomorphism. Conjugation is thus a field isomorphism of C to C.
