Stories About Maxima and Minima (Mathematical World, Volume 1)

In the course of the background of arithmetic, greatest and minimal difficulties have performed a huge function within the evolution of the box. Many appealing and significant difficulties have seemed in a number of branches of arithmetic and physics, in addition to in different fields of sciences. the best scientists of the past---Euclid, Archimedes, Heron, the Bernoullis, Newton, and many others---took half in looking ideas to those concrete difficulties.

History of Mathematics: A Supplement

This ebook makes an attempt to fill gaps which exist within the normal textbooks at the background of arithmetic. One is to supply the scholars with fabric which could inspire extra severe pondering. common textbooks, trying to conceal 3 thousand or so years of mathematical heritage, needs to unavoidably oversimplify almost about every thing, the perform of that may scarcely advertise a serious method of the topic.

Enumeration of Graph Coverings and Surface Branched Coverings

Plenty of graphs having a symmetry estate may be defined as cover-ings of easier graphs. during this manuscript, we study numerous enumeration difficulties for numerous forms of nonisomorphic graph coverings of a graph and a few in their functions to a bunch thought or to a floor thought. This manuscript is geared up as follows.

Beschreibende Statistik: Grundlegende Methoden der Datenanalyse (EMIL@A-stat) (German Edition)

In dem Band werden die Grundlagen und die Methoden der Beschreibenden Statistik erläutert. Wie Tabellen, Graphiken und charakteristische Maßzahlen jeweils eingesetzt werden können, um die wesentlichen Informationen deutlich hervorzuheben, vermitteln die Autoren challenge- und zielorientiert: Zu Beginn jedes Kapitels werden anhand eines Beispiels Fragen der methodengestützte examine diskutiert, dann wird der vorgestellte Datensatz ausführlich bearbeitet, so dass die Methoden und deren Nutzen für Leser anschaulich werden.

Here we will not, of course, be able to discuss all kinds of identities. Far from it. 4) above. The main purpose of this book is to explain how the discoveries and the proofs of hypergeometric identities have been very largely automated. The book is not primarily about computing; it is the mathematics that underlies the computing that will be the main focus. Automating the discovery and proof of identities is not something that is immediately obvious as soon as you have a large computer. The theoretical developments that have led to the automation make what we believe is a very interesting story, and we would like to tell it to you.

Bq k≥0 (b1 )k (b2 )k · · · (bq )k k! 2) The series is well defined as long as the lower parameters b1 , b2 , . . , bq are not negative integers or zero. The series terminates automatically if any of the upper parameters a1 , a2 , . . , it is an infinite series. If the series is well defined and nonterminating, then questions of convergence or divergence become relevant. In this book we will be concerned for the most part with terminating series. 4 Software that identifies hypergeometric series The act of taking a series and finding out exactly which p Fq [.
