But now there is an infinity of possible directions Definition if f0(z) exists and is continuous in some region R.

A function f of a complex variable z is meromorphic in the neighbourhood of a point z 0 if either f or its reciprocal function 1/f is holomorphic in some neighbourhood of z 0 (that is, if f or 1/f is complex differentiable in a neighbourhood of z 0) A zero of a meromorphic function f is a complex number z such that f(z) = 0 A pole of f is a. Solution If f(z) has an isolated singularity at z 0, then clearly exp(f(z)) does too If f(z) has an essential singularity, consider any nonzero c ∈ C By the CasoratiWeierstrass theorem, there is a sequence z n → z 0 such that f(z n) → log(c) So exp(f(z n)) → c Since this is true for all nonzero c, exp(f(z)) must have an.

Theorem 233 If f(z) is analytic in a domain D, then all of its derivatives f(z), f(z), f(z), exist and are themselves analytic Remark This theorem is remarkable because it is unique to complex analysis The analogue for realvalued functions is not true For example, f(x)=9x5/3 for x ∈ R is differentiable.

March 14,08 1 Let f be entire and suppose that the second derivative of f is bounded f00(z) ≤ M for all z ∈ C Prove that f is a polynomial of degree at most 2. Will Garner A 3 Continuing this process out to a10, we have a5 = 0, a6 = 1/42, a7 = 0, a8 = 1/30, a9 = 0, a10 = 5/66 Since we are told that f(z) (1/2)z is an even function, that implies that the power series expansion of f(z) (1/2)z consists only of even powers of z, ie there are no odd powers of z so ak = 0 for k odd and k > 1 So, we have that Bernoulli numbers are given by. Since z 0 is a local maximum for this function also, it follows from the maximum principle that f(z) is constant Then, using the Cauchy–Riemann equations we show that f ′ (z) = 0, and thus that f(z) is constant as well Similar reasoning shows that f can only have a local minimum (which necessarily has value 0) at an isolated zero of f(z).
