Quantum Mechanics Adjoint Operators

Click For Summary
SUMMARY

The discussion focuses on the proof of the property of adjoint operators in quantum mechanics, specifically that the adjoint of the product of two linear operators A and B, denoted as (AB)+, equals the product of their adjoints in reverse order: (B+)(A+). Participants emphasize the importance of understanding the definitions of linear operators and adjoints, particularly in the context of quantum mechanics. The proof relies on the fundamental properties of inner products and linearity.

PREREQUISITES

If we have two linear operators A, and B, where A+ is the adjoint of A, how do we prove the property,

(AB)+=(B+)(A+)

Have you done anything at all? Surely you've invoked the definitions of all terms involved?
