What are the elements of Freudian psychoanalysis in Sons and Lovers?

D.H. Lawrence was aware of Freud's theory, and Sons and Lovers famously uses the Oedipus complex as its base for exploring Paul's relationship with his mother. Paul is hopelessly devoted to his mother, and that love often borders on romantic desire. Lawrence writes many scenes between the two that go beyond the bounds of conventional mother-son love. Completing the Oedipal equation, Paul murderously hates his father and often fantasizes about his death.

Well, frankly speaking, I do not. I myself am preparing for examinations.
