Abstract

DISCUSSIONJ1( .(.ili'(l. This is so because setting x = 0 or // = 0 in equation i:it' gives an integrand of the same form as the integrand in equation 111). The integration proceeds as for equation (37) ;,]),! ea-ily leads to the conclusion that i>/ } is continuous over the philips,/' = 0 and •// = 0.
