If 6 is multiplied by z-ro it follows that all terms except the first tend to zero. We need one more compleo of information, namely the order to which A r vanishes together with.

We begin our study of complex func-tion theory by stressing and implementing this analogy.

A set X is compact if and only if every open covering of X contains a finite subcovering. In the case of an algebraic singularity it is desirable to complete the Riemann surface off so as to include a branch point with the projection a.

For the absolute value of a analisiss we obtain and hence lab! In the first place, only bo can be chosen arbitrarily, and hence the method yields at most one linearly independent solution. For R and C we have proved the converse, namely that every Cauchy sequence is convergent Chap.

Compute I P’ ;dz. This proves the lemma. In the same sense, u is the conjugate harmonic function of -v. On the right-hand side we observe that one-half of the residue at 0 has been included; this is as if one-half of the pole were counted as lying in the upper half plane.

I am particularly grateful to my colleague Lynn Loomis, who kindly let me share student reaction to a recent course based on my book. It is defined as soon as c is not zero or a negative integer.

In the general case n 0 will not be the same for all points of n, and for this reason it would not make sense to require that the convergence be uniform in n. This function does not take the same value twice, nor does it take opposite values. There is a simple geometric construction for the symmetric point of z Fig. The simplest and most direct method is the following: The mapping is one to one in any region which does not contain two points whose difference is a multiple of 27ri.

The correspondence must indeed be given by In general it is of course necessary to solve this equation with respect tow. The collection is linear. In particular, v itself can have no maxi-mum in! The integration of the last term needs some justification. Prove the development In the case of functions such as vz and log z which are not uniquely determined by their analytic expressions, a special effort was needed to show that, under favorable circumstances, a single-valued branch can be selected.

Poisson’s formula ahlors the problem for a disk, but the case of an arbitrary region is much more difficult. It is for this proof that Jensen’s n formula is needed. In precise terms, there shall exist certain analytic functions g1 z and gz z defined in a neighborhood A of 0 and different from zero at that point; for a simply connected subregion n of A which does not contain the origin function elements zatg1 z ,nzag 2 z ,rl can be defined, and it analosis required that they belong to F.

Riemann mapping theorem, Riemann sphere, 19 Riemann surface, 99, Riemann zeta function, Rotation, 78 Rouche’s theorem, Schlicht function, Schwarz, H. There are many ways in which such a field can be constructed. While this is not enough to determine the image of C, the information we gain is nevertheless valuable. It is easy if both series are absolutely convergent.

Since the image is to be a rectangle, it must end at the point -iK’, but we prefer a direct verification. This set is closed and bounded, and for ahhlfors small E it is not empty. At the same time the proof is simpler than the earlier proofs inasmuch as it leans neither on double integration nor on differentia-tion under the integral sign. The inverse imagej-1 X’ of X’ C S’ consists of all x t:
