Riess representation theorem is Riess theorem. In functional analysis, many famous theorems are named Riesz representation theorem, also known as Riesz representation theorem, in memory of Hungarian mathematician Frigyes Riess. This theorem establishes an important connection between Hilbert space and its continuous dual space. If the base field is a real number, they are equidistantly isomorphic; if the field is a complex number, they are equidistantly anti-isomorphic.

Function of theorem

Theorem is a true proposition that is judged to be correct by logical method and used as the basis of reasoning. The essence of mathematical knowledge refers to the knowledge such as arithmetic or formula directly derived from mathematical concepts, and the concept and essence of mathematical knowledge are closely related.
