New fractional pseudospectral methods with accurate convergence rates for fractional differential equations. ETNA - Electronic Transactions on Numerical Analysis
The main purpose of this paper is to introduce generalized fractional pseudospectral integration and differentiation matrices using a family of fractional interpolants, called fractional Lagrange interpolants. We develop novel approaches to the numerical solution of fractional differential equations with a singular behavior at an end-point. To achieve this goal, we present efficient and stable methods based on three-term recurrence relations, generalized barycentric representations, and Jacobi-Gauss quadrature rules to evaluate the corresponding matrices. In a special case, we prove the equivalence of the proposed fractional pseudospectral methods using a suitable fractional Birkhoff interpolation problem. In fact, the fractional integration matrix yields the stable inverse of the fractional differentiation matrix, and the resulting system is well-conditioned. We develop efficient implementation procedures for providing optimal error estimates with accurate convergence rates for the interpolation operators and the proposed schemes in the -norm. Some numerical results are given to illustrate the accuracy and performance of the algorithms and the convergence rates

Dieser Artikel untersucht die Verwendung von Narrativen in Geographieschulbüchern der Sekundarstufe I und II. Die Narrativewerden hinsichtlich ihrer Authentizität, Individualität und Emotionalität analysiert. Es zeigt sich, dass authentischenNarrativen unter allen Schulbuchtexten nur eine marginale Bedeutung zukommt. Individualität und Emotionalität sindlediglich in einem Teil der Narrative zu finden. Für einen verstärkten Einsatz von authentischen Narrativen in Geographieschulbüchernwerden didaktisch begründete Anregungen gegeben

Social Places and Spaces on and beyond Kythera during the Second Palace Period: Exploring the Island’s Landscape and Connectivity. Veröffentlichung der Mykenischen Kommission|(Social) Place and Space in Early Mycenaean Greece Mykenische Studien 35|
The impact of Crete on the societies and material culture of the Greek mainland, particularly in relation tothe emergence of elite groups during the early Mycenaean period, has long been a focus of debate between proponentsof indigenist versus interactionist models of mainland dynamics. The intervening island of Kythera has played animportant role in this phenomenon not least because of its location as a stepping stone between these two distinctivegeographical and cultural regions. The 1960s excavations at the coastal site of Kastri revealed a unique case ofMinoanisation, both due to its early beginnings and its intensity. Understanding of this phenomenon has since beensignificantly enhanced through an intensive field survey that covered one third of the island, as well as through severalexcavations, including those on two peak sanctuaries. What becomes apparent, after c. 2000 BC, is the exclusive presenceof a Cretan-style culture and the lack of any contrastive continuing local tradition, thereby rendering Kythera incultural terms effectively a part of Crete.The intensive field survey results for this period reveal a landscape with dispersed rural settlements and an extensive,multi-focal, potentially urban zone at coastal Kastri. The multidisciplinary study of these two parallel dimensions ofthe island’s landscape provides significant insight into local and regional dynamics. Spatial analysis combined withgeoarchaeological investigations gives a better understanding of the development of the settlement pattern and accompanyingagricultural regimes, while the stylistic and scientific/technological study of material culture (mainly pottery)provides unprecedented knowledge of the island’s craft traditions and their reproduction through time and across space,under strong Cretan influence. Such an approach to the island’s craft products makes even more meaningful the contextualstudy of their spatial distribution both among the numerous communities of the island, but also beyond, amongPeloponnesian groups, so shedding new light on the transfer and reproduction of technological traditions, as well as onconsumer’s preferences and the social context of innovation
GENERAL ASPECTS The Significance of Developments in Peloponnesian Pottery over the Middle to Late Helladic Transition. Veröffentlichung der Mykenischen Kommission|(Social) Place and Space in Early Mycenaean Greece Mykenische Studien 35|
The Peloponnese is often called the heartland of Mycenaean civilisation, and it is certainly possible to followthe processes involved in Mycenaean development more closely through the archaeological material of the Peloponnesethan through that from any other region of mainland Greece. But the Peloponnese was not a unity in the MiddleHelladic period; its different regions show evidence of distinctive characters, not least in their pottery, and show differingpatterns of contact with the outside world. We might therefore expect them to show differences in their developmenttowards Mycenaean, and there is evidence for this, in the pottery as in other features; but there are also indications ofcloser links between the regions, which helped spread the influence of the increasingly prominent northeast and thedevelopment towards the notably homogeneous pottery tradition of later Mycenaean times. This paper will consider theevidence now available for these developments and the motivation that may lie behind them
