But a simple calculation shows that for every complex constant α, f (z) = ¯ | is also extremal. (iii) A more elaborate example is needed to demonstrate the non-uniqueness of an extremal kernel.

Goluzin [1, 2] discussed a wide variety of extremal problems. The first systematic attempt to unify the theory and to extend it to H p (1 ≤ p ≤ ∞) was the paper of Macintyre and Rogosinski [1].

The purpose of this survey paper is to recall the major benchmarks of the theory of linear extremal problems in Hardy spaces and to outline the current status and open problems remaining in Bergman spaces. We focus on. analysing problems can be used as the basis for designing better solutions.

Gábor Székelyhidi. Notre Dame Professor Department of Mathematics A Hurley Notre Dame, IN email: gszekely at I am interested in geometric analysis and complex differential geometry. Much of my work is motivated by trying to find canonical metrics, such as extremal or Kähler-Einstein metrics on projective manifolds.

But the majority of twentieth century polynomial extremal problems ﬁnd their roots in the nineteenth century theory of trigonometric and Fourier series. We will (brieﬂy) mention a few examples in this paper. The reader should, however, ﬁrst read the next section on “peculiarities” of this paper.

Conformal invariants and extremal problems are therefore intimately linked and form together the central theme of this classic book which is primarily intended for students with approximately a year's background in complex variable theory.

Exercises with stars are not a part of mandatory material but are nevertheless worth to hear about.

And they are not necessarily difﬁcult, try to solve them. Remark (i) ^f(n) is a complex number whose modulus is the amplitude.

Since there were a few other pdf level books mentioned above, I thought this answer is also appropriate. Perhaps this book is best for a second course on complex analysis. The first two chapters are content from standard undergraduate complex analysis.
