In functional analysis, the dual norm is a measure of size for a continuous linear function defined on a normed vector space. == Definition == Let X {\displaystyle X} be a normed vector space with norm ‖ ⋅ ‖ {\displaystyle \|\cdot \|} and let X ∗ {\displaystyle X^{*}} denote its continuous dual space.
