{wiki=Positive_operator_(Hilbert_space)}
In the context of Hilbert spaces and functional analysis, a **positive operator** is a specific type of bounded linear operator that acts on a Hilbert space. Here's a more detailed explanation: \#\#\# Definitions and Properties 1. **Hilbert Space**: A Hilbert space is a complete vector space equipped with an inner product, which allows for the generalization of concepts such as length and angle.
