    Excuse me ... .

    A vector or polar-vector can denote as in a tangent space on point at an -dimensional manifold , where is a basis in ... .

    The dot product is a component of metric tensor on the manifold ... .

    For each , the dot product


    is a scalar,

    and the cross product

    is a pseudo-vector alias axial-vector, as I have known ... .

    For each , the triple scalar product is defined as which totally antisymmetric by a permutation ... .

    is a pseudo-scalar, as I have known ... ,

    and the triple vector product

    is a vector alias polar-vector ... .

    The other combinations are

    • is a scalar ... , and

    • is a pseudo-vector alias axial-vector, as I have known ... ,

    for each ... .

    U V UV UV
    [vector] [vector] [scalar] [pseudo-vector]
    [vector] [pseudo-vector] [pseudo-scalar] [vector]
    [pseudo-vector] [vector] [pseudo-scalar] [vector]
    [pseudo-vector] [pseudo-vector] [scalar] [pseudo-vector]

    What do multiplication scalar with scalar, scalar with pseudo-scalar, pseudo-scalar with pseudo-scalar, scalar with vector, scalar with pseudo-vector, pseudo-scalar with vector, and pseudo-scalar with pseudo-vector yield ... ?

    u v uv
    [scalar] [scalar] [scalar]
    [scalar] [pseudo-scalar] [pseudo-scalar]
    [pseudo-scalar] [pseudo-scalar] [???]

    u V uV
    [scalar] [vector] [vector]
    [scalar] [pseudo-vector] [pseudo-vector]
    [pseudo-scalar] [vector] [pseudo-vector]
    [pseudo-scalar] [pseudo-vector] [???]

    What are the two [???] ‘s in the last two tables ... ?

    Are the last two tables right ... ?

    Thank you very much for the answer ... .
