Compact operator on Hilbert space

ID: compact-operator-on-hilbert-space

In functional analysis, a compact operator on a Hilbert space is a specific type of linear operator that has properties similar to matrices but extended to infinite dimensions. To give a more formal definition, consider the following: Let \( H \) be a Hilbert space. A bounded linear operator \( T: H \to H \) is called a **compact operator** if it maps bounded sets to relatively compact sets.
