The following errors have been noticed in our published paper.

-
(i) The signs should be changed to the opposite, on the right sides of the expressions in the following equations. Eq. (2.8) for
$j_r$
and
$j_\phi$
. Eq. (2.11) for the last term. Eq. (2.13) for
$j_r$
and
$j_\phi$
. In the derivatives of Eqs. (3.1), (3.4), (3.5), (3.6), (3.8). Upper term in Eq. (3.10). First term in Eq. (3.15.) -
(ii) The second sentence in the paragraph after Eq. (2.8) should be omitted.
-
(iii) Eqs. (3.8) and (3.16) should have
$b_1(1)=0$
, instead of
$b_1(x_1)=0$
. -
(iv) In Eq. (3.9) the first expression should be written as
$b_1(x)=x^\gamma -1$
-
(v) Figures 3–14 presented here substitute the old ones. The captions to these figures remain the same.
