Secondary literature about Harald Bohr General secondary literature Obituaries Obituaries in non-Danish journals (8) Obituaries in Danish journals (9) Obituaries in newspapers (9) Encyclopedia articles Articles on the World Wide Web General secondary literature about Bohr The most complete work about Bohr and his works is the dissertation by Ramskov (item 1 below), which touches upon most aspects. The many obituaries which exist cover Bohr's life and work from the viewpoint of different persons. The rest of 13 secondary works below touches different aspects of Bohr's works, his importance at the University of Copenhagen, his relationship to the brother Niels Bohr and his football career. Ramskov, Kurt: Matematikeren Harald Bohr [The mathematician Harald Bohr]. Ph.D. dissertation, Institut for de eksakte videnskabers historie, Aarhus Universitet 1995. 451 pp. Ph.D. dissertation in Danish. It is a biography of Bohr which touches upon all aspects of Bohr's life: his mathematical work, his pedagogical importance, his career, as head of the mathematics institute, his help to German mathematical refugees in the 1930s, his fight against "Deutsche Mathematik", his many international contacts and colleagues, his family etc. A detailed discussion is given of his mathematical works before 1932, which include the most important of his works.

Talk:Continued fraction From Wikipedia, the free encyclopedia. XJam [2002.04.02] 2 Tuesday (0) I have seen brackets more often. I don't think it makes much of a difference though. AxelBoldt I can barely follow this page. Firstly, the way it reads, it says that by choosing suitable values, a fraction can be made to equal or at least approach any number. So what? It is in no way clear as to how these numbers are chosen, and the demonstration of finding a series that converges on Pi makes no sense at all. It's like something is being assumed in the discussion that I'm not privy to. Also I wonder if anyone could add to it and say why the theorem was created in the first place - what problem did it solve? As a minor contributor to this page, I decide to attempt a response to the comment above. A continued fraction is just another way to represent a number - on a par with the decimal system or Egyptian fractions . There is a clearly defined way to calculate the elements a n in the continued fraction representation of any given number; this method is demonstrated in the π example, but it might help if the article explained it more directly. The continued fraction representation for some numbers is finite; for others it is infinite. The continued fraction representation for some numbers exhibits a pattern; for others it is apparently random. Continued fractions are of interest to mathematicians because they arise in the

It is a generalisation of the Riemann integral which in some situations is more useful than the Lebesgue integral This integral was first defined by Arnaud Denjoy (1912). Denjoy was interested in a definition that would allow one to integrate functions like This function has a singularity at 0, and is not Lebesgue integrable. However, it seems natural to calculate its integral except over principal value integration or conditional integrability ). In effect, the definitions of Denjoy and Lebesgue agree completely on positive functions. Trying to create a general theory Denjoy used transfinite induction over the possible types of singularities which made the definition quite complicated. Other definitions were given by Nikolai Luzin (using variations on the notions of absolute continuity ), and by

I find your derivation wonderful, now I understand everything. At first, the small writing mistakes on the second page had caused me some difficulties. Now, however, I understand everything. You should publish the theory in this new form in the Annals of Physics since the physicists do not normally know anything about this subject as was also the case with me. With my letter I must have come across to you like a Berliner who had just discovered Grunewald and wondered whether people were already living there. If you wouldn't mind also making the effort to present to me the canonical transfromations, you'll find in me a grateful and attentive audience. If you, however, answer the question about the closed time trajectories, I will appear before you with my hands folded. The underlying truth, though, is well worth some perspiration. Best regards, your Albert Einstein. Albert Einstein The previously mentioned letter of Einstein was part of their correspondence about Hamilton-Jacobi theory. Albert Einstein had then around 1912 set aside his thoughts and ideas regarding general relativity theory and hoped with the help of the tools of Hamilton-Jacobi to arrive at deeper insights.

This web page uses gif images ( underlines , and super scripts and sub An Introduction to The Gauge Integral also known as the generalized Riemann integral, the Henstock integral, the Kurzweil integral, the Henstock-Kurzweil integral, the HK-integral, the Denjoy-Perron integral, etc. by Eric Schechter , version of 13 July 2005. Your comments are invited. Historical and Bibliographical Overview Integrals and derivatives were already known before Newton and Leibniz. Those two mathematicians are generally credited with inventing Calculus around 1670 because they developed its Fundamental Theorem i.e., that areas are essentially the same thing as antiderivatives. Later, Cauchy investigated the integrals of continuous functions. Still later, Riemann refined the definition that Cauchy had been using, and investigated the integrals of discontinuous functions. The Riemann integral is simpler to define than any of the other integrals discussed below, and it is the "standard" integral that we teach to undergraduate students. Still, it is more complicated than the antiderivative, and it seems to be beyond the understanding of many undergraduate students. The theory of the Riemann integral was not fully satisfactory. Many important functions do not have a Riemann integral even after we extend the class of integrable functions slightly by allowing "improper" Riemann integrals. Moreover, even for integrable functions, it is difficult to prove good convergence theorems using only the tools ordinarily associated with Riemann integrals. A pointwise, bounded limit of Riemann integrable functions is not necessarily Riemann integrable. (For instance, since the rationals are enumerable, the characteristic function of the rationals can be represented as the pointwise limit of a sequence of characteristic functions of finite sets.)

CONTINUED FRACTIONS The continued fraction of the square root of 2 is If you already know what this means, skip a few paragraphs. Otherwise, some introductory remarks are needed. For any real number R, let [R] be the greatest integer less than or equal to R, and fractional part of R). F(K+1) = 1/((F(K)-A(K))), for K = 0, 1, 2, . . . , and F(0) = R. If you try this out on R = square root of 2, you'll find A(0) = 1, A(1) = 2, A(2) = 2, A(3) = 2, A(4) = 2, A(5) = 2, and so on. The sequence A(K) is written in the form [A(0), A(1), A(2), . . . ] and has been known for several hundred years as the continued fraction of R . The reason for the name is indicated by the pictured equation. The continued fraction of R is studied largely through the behavior of a sequence of rational numbers called the convergents to R. To define convergents, begin with P(-2) = 0, P(-1) = 1, P(I) = A(I)P(I - 1) + P(I - 2) and Q(-2) = 1, Q(-1) = 0, Q(I) = A(I) Q(I - 1) + Q(I - 2), for I = 0, 1, 2, . . . . The convergents of R are the rational numbers P(I)/Q(I). The limit of the convergents is R. In fact, P(I)/Q(I) is called a

Münchner Mathematisches Kolloquium Am Freitag, 01. Juli 2005, um 16 Uhr c.t. spricht Prof. Roger Nussbaum, Ph. D. Rutgers University Perron-Frobenius Theory and Games by the Seashore Zusammenfassung: Almost one hundred years ago Perron and Frobenius developed a beautiful theory concerning eigenvalues and eigenvectors of nXn matrices A all of whose entries are nonnegative. If A is such a matrix and all the columns of a sum to one (so A is a column stochastic matrix), then for every nonnegative nX1 column vector x, there is a column vector y and an integer p such that A^kp(x) converges to y as k goes to infinity. Furthermore, p is the order of some element of the symmetric group on n letters. Over the past twenty years, some remarkably precise analogues of the above result have been obtained for classes of nonlinear maps. Surprisingly, all of the basic difficulties are already apparent in a simple sand-shifting game which a mathematically inclined child might play by the seashore. We shall describe this sand-shifting game, give some theorems and discuss some open questions. Alle Interessierten sind hiermit herzlich eingeladen. Eine halbe Stunde vor dem Vortrag gibt es Kaffee und Tee im Sozialraum (Raum 448) im 4. Stock.
