A **projective Hilbert space** is a mathematical concept that arises in both quantum mechanics and functional analysis. It is specifically related to the idea of "quantum states" and the representation of these states in a Hilbert space. \#\#\# Definition: 1. **Hilbert Space**: A Hilbert space is a complete inner product space, which is a fundamental concept in quantum mechanics.
