I am reading Anderson and Feil - A First Course in Abstract Algebra.
I am currently focused on Ch. 24: Abstract Groups ... ...
I need some help in understanding some claims in Chapter 24 by Anderson and Feil ... ...Anderson and Feil claim that $$\text{Aut} ( \mathbb{C} ) $$is a group with only two elements $$\{i, f \}$$ ... ... where $$i$$ is the identity automorphism and $$f$$ is the complex conjugation map defined by $$f(a + bi) = a - bi$$ ... ...
... can someone please help me to prove the assertion that $$\text{Aut} ( \mathbb{C} ) $$is a group with only two elements $$\{i, f \}$$ ...
