Thus R ( ui ; T + P ) exists and equals C , proving by Definition 2.1 that T + P is discrete . Since by hypothesis D ( T - 1P ) 2 D ( T ' ) for 15 k , it follows that PD ( T ) = D ( T - 1 ) ...

Moreover , it follows similarly that at a point de eR for which pol > 82 but for which A ( 10 ) = 0 , R ( A ) has a pole of order at most equal to the order of the zero of A ( a ) at 1o . Finally , if 0 < ^ , < oo and A + ( 91 ) +0 ...
