identifying the conformal transformation group, namely of type translation (parameters α 0 and
β 0 ), of type rotation (parameter α 1 ), of type dilatation (parameter β 1 ), and of type special-
conformal (parameters α 2 and β 2 ) up to order three (O 3 ), actually the six-parameter subalgebra
C 6 (2) of the infinite dimensional algebra C (2) in two dimensions
2 . Note that the
rotation parameter α 1 operates on the antisymmetric matrix ( 16.18 ), while the matrices ( 16.19 ),
which generate the special conformal transformation, are traceless and symmetric.

16-2 The Oblique Reference Frame
Oblique reference frame and normal reference frame, central oblique plane, circle-reduced
meta-longitude and circle-reduced meta-pole.
In the following discussion, let us orientate a set of orthonormal base vectors { e 1 , e 2 , e 3 } along
the principal axes of
[( x 1 ) 2 +( x 2 ) 2 ] A 1 +( x 3 ) 2 A 2 =1 ,A 1 R

Against this frame of reference

(consisting of the base vectors e i , and the origin
O
). we introduce the oblique one
{
e 1 , e 2 , e 3 ,

by means of ( 16.20 ) illustrated by Fig. 16.3 .
