On the other hand , it follows from the asymptotic formula ( 26 ) and from the
formula ( 21 ) giving the form of the kernel defining the operator Gu that if we
excise from the angle A of the u - plane ( defined by formula ( 8 ) ) a circle of
radius ε ...

It follows immediately from formulas ( 52 ) and ( 34 ) that ( B , Guf ) can be written
in the form ( 55 ) ( B , Gus ) = - n Tex ( de ) ... Moreover , formula ( 56 ) may clearly
be differentiated any number of times with respect to x , and still remain a valid ...
