Note 1 to entry: The inner product of two vectors is their scalar product, because a tensor of the first order is considered as a vector.

Note 2 to entry: An example is the relation D= ε E MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiaahseacqGH9aqpda WhkaqaamaaFOaabaGaeqyTdugacaGLrdcaaiaawgniaiabgwSixlaa hweaaaa@3F4D@ between the electric field strength E and the electric flux density D, where ε MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiaayIW7daWhkaqaam aaFOaabaGaeqyTdugacaGLrdcaaiaawgniaaaa@3BF3@ is the absolute permittivity of an anisotropic medium.
