In class we showed that if f ( z ) is a holomorphic function with simple isolated zeroes located at a 1 , a 2 , · · · , none of the a i zero, then f ( z ) could be written in terms of f (0), f p (0), and the a i as f ( z ) = f (0) exp p z f p (0) f (0) P ± n ² 1 - z a n ³ exp( z/a n ) 1. Suppose f ( z ) is an N th order polynomial: f ( z ) = α ( x - x 1 )( x - x 2 ) · · · ( x - x N ) for α some constant and none of the x i vanishing. Show that the expression above correctly captures the polynomial nature of f ( z

Unformatted text preview: ). In other words, plug in f (0), f p (0), and the locations of the zeroes, and verify that the abstract formula at top reduces to the N th order polynomial above. 2. The function 1 / ( z + 1) can be shown to have simple zeroes at z =-1 ,-2 ,-3 , . Use the formula above to derive the Weierstrass representation of 1 / ( z )....
