Basefield transforms derived from character tables

چکیده
We show that it is possible to de ne Hartley-like transforms for (generalized) character tables of nite groups. This large class of transforms include Hartley transforms for discrete Fourier transforms over abelian groups and Hartley-like transforms for the discrete cosine transform of type I.

Hartley transforms over finite fields
A general f ramework is presented for constructing transforms in the field of the input which have a convolutionlike property. The construction is carried out over finite fields, but is shown to be valid over the real and complex fields as well. It is shown that these basefield transforms can be v iewed as “projections” of the discrete Fourier transform @IT) and that they exist for all lengths ...

متن کاملCharacter tables of the association schemes of finite orthogonal groups acting on the nonisotropic points
It is shown that the character tables of the association schemes in the above (i) and (ii) are controlled by the character table of the group PSL(2, q), while that the character tables of the association schemes in (iii) are controlled by the character tables of the association schemes obtained from the action of the group PGL(2, q) acting on the cosets by dihedral subgroups D,,,_ , , and D,,,+...
