    Only with this attitude, one can "internalize" the analytic continuation that is so natural in so many contexts in modern physics. The concept of "natural boundary" is entirely appropriate for this article, but the theorems about which power series have Analytic continuation of group representations book natural boundary are too removed from the subject of analytic continuation. I think it is fair to say that there are several confusing points, even if other potentially confusing points can be cleared up by "standard mathematics". Since the terms of a conditionally convergent series can be re-arranged to give any value we choose, one might wonder if analytic continuation — which is based so fundamentally on conditional convergence — really gives a unique result. On the other hand, in classical electromagnetism, the complex amplitudes for various electromagnetic waves and oscillating circuits are just a "useful tool" that doesn't have to be considered fundamental or real. Also: All the stuff about natural boundaries should have its own article.

    First, the author, bearing in mind the needs of the physicist, has tried to make the exposition as elementary as possible. Complex numbers are "truly fundamental" in some physical contexts and at least "very useful tricks" in others. It is therefore an important problem in the theory of analytic continuation of functions of several complex variables to describe these larger domains — the so-called envelopes of holomorphy. And I could continue for a while. Proving the equality of the two combinatorial definitions of the Weyl group multiple Dirichlet series requires the comparison of two sums of products of Gauss sums over lattice points in polytopes.

    The last two chapters concern Eichler-Shimura theory, which establishes a much deeper relationship between the two subjects. This part depends on some "somewhat advanced" mathematics and an intuitively, emotionally based person interested in physics has probably never expected that he would have to learn such mathematical things to understand the behavior of physical systems. I've examined the picture file on Wikimedia Commonsbut that doesn't give any indication of the tools used for creating it, so we'd have to start from scratch or try to persuade the original creator to improve the graphic. Furthermore, their coefficients are multiplicative up to roots of unity, generalizing the notion of Euler products.

One must ultimately make this transition to understand modern physics and especially to be able to do calculations. The need for an elementary exposition has influenced the distribution of the material; the book is divided into three largely independent parts, arranged in order of increasing difficulty.

These include various analytic representations: parameter-dependent Analytic continuation of group representations book such as Cauchy-type integrals cf. The same applies to the series for the other coefficients. The top of g is the value of f at z0, the bottom of g.

The idea of finding the maximal analytic continuation of a function in turn led to the development of the idea of Riemann surfaces. The field of analytic continuation also includes theorems on removable singularities removability of an isolated singularity of a bounded holomorphic function, removability of a rectifiable singular curve under conditions of continuity, etc.

Like the Riemann zeta function, they are Dirichlet series with analytic continuation and functional equations, having applications to analytic number theory. Riemann—Schwarz principlefunctional and differential equations satisfied by a function e.

Also: All the stuff about natural boundaries should have its own article. This general process of analytic continuation is not very effective in practice, and for this reason many special methods of analytic continuation are employed.

analytic continuation

Star of a Analytic continuation of group representations book element ; Mittag-Leffler summation methodetc. Weyl group multiple Dirichlet series are generalizations of the Riemann zeta function. I have a B. Because the mathematical facts about the analytic continuation are so useful and universally applicable, one should better get rid of any negative emotions and hostility towards them as quickly Analytic continuation of group representations book possible.

However, it actually is possible to analytically continue the geometric series, but only because of conditional convergence. And I could continue for a while. F1 - F2? In analytic continuation, the center of each disk in a sequence of function elements must lie inside the previous disk.

When it's real, it's just a special case. Any recommendations for suitable graphic tools for illustrating complex analysis? I think it is fair to say that there are several confusing points, even if other potentially confusing points can be cleared up by "standard mathematics".

In Analytic continuation of group representations book limiting case only the first-order term of the geometric series is significant, so we have Therefore the integral of the right hand side reduces to from which it follows as we would expect that Another important aspect of analytic continuation is the fact that the continuation of a given power series to some point outside the original region of convergence can lead to different values depending on the path taken.

This is consistent with the fact that the natural log function i. The overall message is that the insights of modern physics have shown the we have thought about these matters in a wrong way when we were thinking that the real numbers were fundamental. Furthermore, their coefficients are multiplicative up to roots of unity, generalizing the notion of Euler products.

Granting some such assertion, the remainders of the arguments are relatively formal. Colin-de-Verdiere's argument works well in rank 1, but, in its nascent form, has the same limitations as Selberg's s viewpoint. I'm pretty sure I can come up with some other examples Daqu talk12 January UTC Natural boundary[ edit ] The current article states that "The circle is a natural boundary if all its points are singular.

Writing[ edit ] Is there some chance that someone who has both an understanding of the mathematics and a reasonable ability to write comprehensibly might take a pass over this article? This is yet another place where a bit of history would help readers immeasurably in understanding the motivations of, and the paths taken, by the mathematicians who pioneered these techniques.

Through a series of surprising combinatorial reductions, this is accomplished.The paper deals with the general background connecting the ideas of analytic continuation and contraction of Lie algebras and their representations.
