This monograph deals with symmetries of compact Riemann surfaces. A symmetry of a compact Riemann surface S is an antianalytic involution of S. It is well known that Riemann surfaces exhibiting symmetry correspond to algebraic curves which can be defined over the field of real numbers. In this monograph we consider three topics related to the topology of symmetries, namely the number of conjugacy classes of symmetries, the numbers of ovals of symmetries and the symmetry types of Riemann surfaces.
Poland's anti-constitutional breakdown poses three questions that this book sets out to answer: What, exactly, has happened since 2015? Why did it happen? And what are the prospects for a return to liberal democracy?
The role of Western NGOs in the transition of postcommunist nations to democracy has been well documented. In this study, Paulina Pospieszna follows a different trajectory, examining the role of a former aid recipient (Poland), newly democratic itself, and its efforts to aid democratic transitions in the neighboring states of Belarus and Ukraine. Belarus is widely regarded as the most authoritarian state in the region, while Ukraine is witnessing a slow, if often troubled, democratic consolidation. Each state presents a different set of challenges to outside agencies. As Pospieszna shows, Poland is uniquely positioned to offer effective counsel on the transition to democracy. With similariti...
This volume contains the proceedings of the conference on Riemann and Klein Surfaces, Symmetries and Moduli Spaces, in honor of Emilio Bujalance, held from June 24-28, 2013, at Linköping University. The conference and this volume are devoted to the mathematics that Emilio Bujalance has worked with in the following areas, all with a computational flavor: Riemann and Klein surfaces, automorphisms of real and complex surfaces, group actions on surfaces and topological properties of moduli spaces of complex curves and Abelian varieties.
Selected papers presented at the international conference on group theory held at St. Andrews in 1989 are combined in two volumes. The themes of the conference were combinatorial and computational group theory.
Over the last decade, the world has watched in shock as populists swept to power in free elections. From Manila to Warsaw, Brasilia to Budapest, the populist tide has shattered illusions of an inexorable march to liberal democracy. Eschewing simplistic notions of a unified global populism, this book unpacks the diversity and plurality of populisms. It highlights the variety of constitutional and extraconstitutional strategies that populists have used to undermine the institutional fabric of liberal democracy and investigates how ruling populists responded to the Covid-19 crisis. Outlining the rise of populisms and their governing styles, Wojciech Sadurski focuses on what populists in power do, rather than what they say. Confronting one of the most pressing concerns of international politics, this book offers a vibrant, contemporary account of modern populisms and, significantly, considers what we can do to fight back.
Based on extensive empirical work by a cross-European group of researchers, this book assesses the impact of the creation of the European External Action Service (EEAS) on the national foreign policy-making processes and institutions of the EU member states. As such, the contributions cover both the involvement of the national diplomatic and foreign policy actors in shaping the outlook of the EEAS and its mission, as well as the changes (or not) it has produced for those actors of the member states. The analysis draws in theoretical frameworks from Europeanization and socialization, but also from intergovernmental frameworks of policy-making within the European Union. An introduction by the ...
Europe Undivided analyzes how an enlarging EU has facilitated a convergence toward liberal democracy among credible future members of the EU in Central and Eastern Europe. It reveals how variations in domestic competition put democratizing states on different political trajectories after 1989, and how the EU's leverage eventually influenced domestic politics in liberal and particularly illiberal democracies. In doing so, Europe Undivided illuminates the changing dynamics of the relationship between the EU and candidate states from 1989 to 2004, and challenges policymakers to manage and improve EU leverage to support democracy, ethnic tolerance, and economic reform in other candidates and proto-candidates such as the Western Balkan states, Turkey, and Ukraine. Albeit not by design, the most powerful and successful tool of EU foreign policy has turned out to be EU enlargement - and this book helps us understand why, and how, it works.
The enlarged European Union needs new instruments for exporting stability and change into the fragile regions and countries beyond its borders. That is why the EU is developing and implementing the European Neighbourhood Policy (ENP): a strategic concept which is to enhance the Union ́s capability to be a driver of reform - without automatically promising the ""golden carrot"" of membership to the neighbours. This book provides the reader with information on what ENP wants, how it works and what the prospects of the Union ́s cooperation with neighbouring countries are.
