VECTOR SPACE OF LINEAR FUNCTIONALS (MAY CONSIST ONLY ON CONTINUOUS FUNCTIONALS OR OF ALL FUNCTIONALS)
Duality (linear algebra); Dual vector space; Algebraic dual; Continuous dual; Continuous dual space; Algebraic dual space; Norm dual; Double dual; Topological dual space; Dual (linear algebra); Annihilator (linear algebra); Dual Space
In mathematics, any vector space V has a corresponding dual vector space (or just dual space for short) consisting of all linear forms on V, together with the vector space structure of pointwise addition and scalar multiplication by constants.
