Henceforth, the IVi II gjj 11/2 will be called the componentst of v, because of their intuitive significance. When written out in these components, many formulas lose their simplicity. A diffeomorphism M2 )0 T*(< x I ----------+, T(M 1) 2 M2 X ~ )(1) T*(<

Ir are the components of the tensors, and are the quantities usually called tensors in physics. The tensor product of r arbitrary vectors is defined t Following the usual convention we use subscripts for the bases and superscripts for the components in a tangent space, and do it the other way around in a cotangent space. This does not fix what to do about coordinates, which are not vectors. 4 Tensors similarly to the tensor product of basis elements. Not every tensor can be written in the form VI ® V2 ® ...

A vector remains unchanged under a displacement, but one must take care to talk only about a vector at one particular point, which has different coordinates in the new system. 2.
