Sommario/riassunto |
|
This book is intended to serve as a one-semester introductory course in number theory. Throughout the book a historical perspective has been adopted and emphasis is given to some of the subject's applied aspects; in particular the field of cryptography is highlighted. At the heart of the book are the major number theoretic accomplishments of Euclid, Fermat, Gauss, Legendre, and Euler, and to fully illustrate the properties of numbers and concepts developed in the text, a wealth of exercises have been included. It is assumed that the reader will have |

|
'pencil in hand' and ready access to a calculator or computer. For students new to number theory, whatever their background, this is a stimulating and entertaining introduction to the subject. |

Sommario/riassunto |
|
In Avar-Age Polearms and Edged Weapons , Gergely Csiky offers a presentation of close combat weapons of a nomadic population that migrated from Inner Asia to East-Central Europe. During the late 6th – early 7th centuries, the Avars led successful military campaigns against the Balkan realms of the Byzantine Empire, facilitated by their cavalry’s use of stirrups for the first time in Europe. Besides the classification, manufacturing techniques, fittings, suspension, distribution, and chronology of polearms and edged weapons known from Avar-age burials, a special emphasis is laid on the origins and cultural contacts of these weapons, among them the first edged weapons with curved blades: the sabres. The social significance and, function of these |

artefacts is discussed in order to place them in nomadic warfare. |
