We discuss the construction of bases of functions in subspaces Y of a (finite-dimensional) linear space X that are dual to certain certain subsets of X∗. Or, in inner product spaces, we construct dual basis functions in one subspace Y1 that are dual to bases in a second subspace Y2. The constructions and properties are applied to subspaces of polynomials spaces in the B-form.
