 Representation theorem

The term "Representation Theorem" can refer to several concepts across various fields of mathematics, including functional analysis, probability theory, and economics. Here are a few notable examples: 1. **Representation Theorem in Functional Analysis**: In the context of functional analysis, one important representation theorem is the Riesz Representation Theorem. This theorem states that every continuous linear functional on a Hilbert space can be expressed as an inner product with a fixed element of the space.
