Denote this particular solution by U r . Then,
t r =(−ω) U r ,

where
(−1) M j (c)f r (x j )

U r = (6.10.54)

and the symbol ∗ denotes the complex conjugate. This function is of the
form (4.13.3), where
(−1) j−1 M j (c)

and N =2n. These choices of a j and N modify the function k r defined in
(4.13.5). Denote the modified k r by w r , which is given explicitly in (6.10.3).
Since the results of Section 4.13.2 are unaltered by replacing ω by (−ω),
it follows from (4.13.22) and (4.13.23) with n → m that

Since τ j = ρε j , (the third line of (6.10.26)), the functions F and G defined
in Section 6.2.8 are given by
