This classic work by the late Stefan Banach has been translated into English so as to reach a yet wider audience. It contains the basics of the algebra of operators, concentrating on the study of linear operators, which corresponds to that of the linear forms a1x1 + a2x2 + ... + anxn of algebra.The book gathers results concerning linear operators defined in general spaces of a certain kind, principally in Banach spaces, examples of which are: the space of continuous functions, that of the pth-power-summable functions, Hilbert space, etc. The general theorems are interpreted in various mathematical areas, such as group theory, differential equations, integral equations, equations with infinitely many unknowns, functions of a real variable, summation methods and orthogonal series.A new fifty-page section (``Some Aspects of the Present Theory of Banach Spaces'') complements this important monograph.

Focusing on the immigrant family, this title brings together documents and commentary that is suitable for teaching United States history survey courses as well as immigration history and introductory sociology courses. It includes an introduction and epilogue.

One can often encounter an opinion that Polish scientific (or analytic) philosophy (or the Lvov-Warsaw School) deserves to be much better known than actually is. This book is thought as a response to such a claim. The papers collected in this volume are divided into two parts: Background and Influence and History and Systematics. However, there is no sharp borderline between themes which are touched in both parts. Generally speaking, all papers of the first part relate the Lvov-Warsaw School to some philosophical movements (Brentanism, phenomenology and Marxism) external to it whereas the papers collected in the second one focus on internal issues connected with the school (only Roberto Poli takes into account Brentano's views in his discussion of reism). Since the Polish school of mathematical logic is much better known than the Polish analytic philosophy we decided to omit here any treatment of the former. Thus, this collection centers on purely philosophical matters. We projected this volume not as an exhaustive panorama of Polish analytic philosophy but rather as a series of essays on particular persons or topic. As a result one can find here papers on Twardowski. Ajdukiewicz, Kotarbinski, Tarski and Lukasiewicz as well as on ethics on science, nominalism, and the methodology of psychology. We hope that this book will contribute to a better knowledge and evaluation of Polish achievements in analytic philosophy. We would like to express our gratitude to Professor Leszek Nowak, the editor-in-chief of Poznan Studies in the Philosophy of the Sciences and the Humanities, who initiated the idea of the collection and helped in its preparation.

Rising Subjects explores the change of the public sphere in Russian Poland during the 1905 Revolution. The 1905 Revolution was one of the few bottom-up political transformations and general democratizations in Polish history. It was a popular rebellion fostering political participation of the working class. The infringement of previously carefully guarded limits of the public sphere triggered a powerful conservative reaction among the commercial and landed elites, and frightened the intelligentsia. Polish nationalists promised to eliminate the revolutionary “anarchy” and gave meaning to the sense of disappointment after the revolution. This study considers the 1905 Revolution as a tipping point for the ongoing developments of the public sphere. It addresses the question of Polish socialism, nationalism, and antisemitism. It demonstrates the difficulties in using the class cleavage for democratic politics in a conflict-ridden, multiethnic polity striving for an irredentist self-assertion against the imperial power.
