Operators and Iterative Processes of Fejér Type
This book, written by two experts in the field, deals with classes of iterative methods for the approximate solution of fixed points equations for operators satisfying a special contractivity condition, the Fejér property. The book is elementary, self-contained and uses methods from functional analysis, with a special focus on the construction of iterative schemes. Applications to parallelization, randomization and linear programming are also considered.

Feynman Integral and Feynman's Operational Calculus
The aim of this book is to make accesible to mathematicians, physicists and other scientists interested in quantum theory, the mathematically beautiful but difficult subjects of the Feynman integral and Feynman's operational calculus Some advantages of the four approaches to the Feynman integral which are given detailed treatment in this book are the following: the existence of the Feynman integral is established for very general potentials in all four cases; under more restrictive but still broad conditions, three of these Feynamn integrals agree with one another and with the unitary group from the usual approach to quantum dynamics; these same three Feynman integrals possess stability properties. Much of the material covered here was previously available only in the research literature, and the book also contains some recent results. The background material in mathematics and physics that motivates the study of the Feynman integral and Feynman's operational calculus is discussed and detailed proofs are provided for the central results.

Leopold Fejér Gesammelte Arbeiten I
>an asymptotisch darstellt-, wenn . a;n 1 1m--= 1, n=oow(n) oder anders ausgedruckt, wenn a: n = w(n) (1 + Bn), wobei Wir werden dies mit bezeichnen. Zur Bestimmung eines solchen asymptotischen Ausdrucks w(n) hat DAR Boux1 eine sehr allgemeine Methode gegeben. Er bildet die Potenzreihe (1) der komplexen Veranderlichen z und zeigt, dass der asymptotische Wert von a: n von denjenigen Singularitatastellen der analytischen Funktion f(z) abhangt, die auf der Peripherie des Konvergenzkreises der Potenzreihe (1) liegen. Ich werde jetzt mit einigen Worten die DARBOUXschen Resultate dar legen. Damit die DARBouxsche Methode anwendbar sei, muss notwendigerweise vorausgesetzt werden, dass der Radius des Konvergenzkreises der Potenz reihe (l) eine von Null und von + oo verschiedene positive Zahl R ist. Nehmen wir ferner an, dass die Anzahl der Singularitatastellen (JylJ = \Y2\ = . . . = JykJ = R) der Funktionf(z) (eigentlich der durch die Reihe (1) gewinnbaren unmittel baren analytischen Fortsetzung derselben) auf dem Konvergenzkreis mit dem Radius R endlich ist. Da nun DARBOUX beweist, dass die Singularitata stellen Yv y,, Yk solche >>Teile"

Federalist Alternative for European Governance
How did the European Union (EU) deal with the crises of the 2010s and 2020s? These crises arose in policy realms that were the province of national governments, so the European Council was the driving institution for managing them. National governments were able to take decisions, but their decisions were contradictory and unaccountable, and regularly hindered by divisions between them. In order to manage a policymaking process dominated by the claims of national and sub-regional governments, Sergio Fabbrini argues that intergovernmental governance has had to transform the EU into an international organization. Fabbrini shows that differentiated integration would further distance the EU from the project of an 'ever closer union' and, on the basis of a comparative federalism approach, he proposes an alternative paradigm of a multi-tier Europe with a federalist core to balance national sovereignties and supranational authority.

Manuel de N�jera, Decano de Predicadores
Manuel de N�jera fue uno de los predicadores m�s aclamados de la Espa�a del siglo XVII. Miembro de la Compa��a de Jes�s, se hizo famoso por su carrera en los p�lpitos, llegando a consolidarse como uno de los predicadores reales m�s importantes del reinado de Felipe IV. Y, sin embargo, es muy poco lo que sabemos sobre �l. En este volumen colectivo, participan especialistas en el �mbito de la oratoria sagrada que presentar�n trabajos directamente relacionados con la figura de N�jera y su �poca. Los diferentes cap�tulos ya plantean nuevas propuestas dentro del �mbito de la predicaci�n, estudios literarios del Siglo de Oro, la Nueva Historia Pol�tica y una Historia de la Iglesia renovada. Adem�s de estudiar en mayor profundidad aspectos esenciales de la vida y obra de Manuel de N�jera, se resaltar� tambi�n su papel en la Real Capilla de Felipe IV y Carlos II, la instrumentalizaci�n pol�tica de la oratoria sagrada, la relaci�n de los predicadores con las �lites y, por supuesto, el papel que jug� la Compa��a de Jes�s en la pol�tica y religi�n de su tiempo. En definitiva, se trata de un volumen colectivo que presenta nuevas interpretaciones, as� como la reinterpretaci�n de algunas tendencias cl�sicas, utilizando a N�jera y su universo como puntos de referencia.

Feyerabend in Dialogue
This book offers innovative historical scholarship on Feyerabend’s take on topics such as realism, empiricism, pluralism, materialism, and incommensurability. In addition to discussing certain debates in the philosophy of physics, it also considers the ways in which Feyerabend’s thought can contribute to contemporary debates in science and public policy. It does so by including questions about the nature of scientific methodology, the role of science in society, the public understanding of science, scientism, and the role of expertise in public policy. The chapters provide readers with a comprehensive overview of the topics that Feyerabend engaged with throughout his career, showing both the breadth and the depth of his thought. Though of great value to academics in philosophy of science, it is also accessible and appealing to non-academic audiences with a general interest in science.
