  • is a set of vectors that spans a finite-dimensional algebraic dual space
  • given aĀ vector space š‘‰Ā with aĀ basis šµĀ ofĀ vectorsĀ indexed by anĀ index set š¼Ā (theĀ cardinalityĀ of š¼Ā is the dimension of š‘‰), theĀ dual setĀ of šµĀ is a set šµ*Ā of vectors in theĀ dual space š‘‰*Ā with the same index set š¼ such that šµĀ and šµ*Ā form aĀ biorthogonal system. The dual set is alwaysĀ linearly independentĀ but does not necessarilyĀ span š‘‰*. If it does span š‘‰*, then šµ*Ā is called theĀ dual basisĀ orĀ reciprocal basisĀ for the basis šµ.
  • is a (1,0)-tensor
