Björn Gustafsson - Böcker

This comprehensive Handbook addresses a wide range of issues concerning inequality in contemporary China and its recent past. It covers diverse forms of inequality faced by Chinese citizens, from wage and income disparities to employment, education, the role of social insurance and public revenues.Björn Gustafsson and Xiuna Yang bring together a range of leading specialists from China and the wider global community to discuss the country’s profound transformation since the late 1980s. They outline how China has transitioned from a low-income country to an upper middle-income country, illustrating its shift from a planned economy to one in which the state plays a considerably smaller role. Contributing authors explore China’s rapid urbanization and the impact of this on living standards and the wellbeing of citizens. The Handbook also examines educational access and child inequality, delving into recent policies on housing as well as trends in household wealth, health and happiness.The Handbook on Inequality in China is a vital resource for students and academics in Chinese studies, economics, social policy and sociology. Policymakers will greatly benefit from its breadth of research into the economic complexities of life in contemporary China.

This title was first published in 2000:  The Nordic Council and the Nordic Council of Ministers decided in 1994 to initiate and finance a comparative study to understand better the structure and development of poverty in five Nordic countries, (Denmark, Finland, Iceland, Norway and Sweden). The main question posed is how the number of people living with low incomes has changed over time and what characterizes such households.? Since no official poverty line has been defined in the Nordic countries, the comparative study examines a set of different definitions of poverty and analyzes the change in poverty rates and poverty composition in light of those different definitions.

This book studies solutions of the Polubarinova–Galin and Löwner–Kufarev equations, which describe the evolution of a viscous fluid (Hele-Shaw) blob, after the time when these solutions have lost their physical meaning due to loss of univalence of the mapping function involved.

This monograph covers a multitude of concepts, results, and research topics originating from a classical moving-boundary problem in two dimensions (idealized Hele-Shaw flows, or classical Laplacian growth), which has strong connections to many exciting modern developments in mathematics and theoretical physics. Of particular interest are the relations between Laplacian growth and the infinite-size limit of ensembles of random matrices with complex eigenvalues; integrable hierarchies of differential equations and their spectral curves; classical and stochastic Löwner evolution and critical phenomena in two-dimensional statistical models; weak solutions of hyperbolic partial differential equations of singular-perturbation type; and resolution of singularities for compact Riemann surfaces with anti-holomorphic involution. The book also provides an abundance of exact classical solutions, many explicit examples of dynamics by conformal mapping as well as a solid foundation of potential theory. An extensive bibliography covering over twelve decades of results and an introduction rich in historical and biographical details complement the eight main chapters of this monograph.Given its systematic and consistent notation and background results, this book provides a self-contained resource. It is accessible to a wide readership, from beginner graduate students to researchers from various fields in natural sciences and mathematics.

This book exploits the classification of a class of linear bounded operators with rank-one self-commutators in terms of their spectral parameter, known as the principal function. The resulting dictionary between two dimensional planar shapes with a degree of shade and Hilbert space operators turns out to be illuminating and beneficial for both sides. An exponential transform, essentially a Riesz potential at critical exponent, is at the heart of this novel framework; its best rational approximants unveil a new class of complex orthogonal polynomials whose asymptotic distribution of zeros is thoroughly studied in the text. Connections with areas of potential theory, approximation theory in the complex domain and fluid mechanics are established.The text is addressed, with specific aims, at experts and beginners in a wide range of areas of current interest: potential theory, numerical linear algebra, operator theory, inverse problems, image and signal processing, approximationtheory, mathematical physics.

Quadrature domains were singled out about 30 years ago by D. Aharonov and H.S. Shapiro in connection with an extremal problem in function theory. Since then, a series of coincidental discoveries put this class of planar domains at the center of crossroads of several quite independent mathematical theories, e.g., potential theory, Riemann surfaces, inverse problems, holomorphic partial differential equations, fluid mechanics, operator theory. The volume is devoted to recent advances in the theory of quadrature domains, illustrating well the multi-facet aspects of their nature. The book contains a large collection of open problems pertaining to the general theme of quadrature domains.

This monograph presents recent and new ideas arising from the study of problems of planar fluid dynamics, and which are interesting from the point of view of geometric function theory and potential theory. the book is concerned with geometric problems for Hele-Shaw flows. Additionally, Hele-Shaw flows on parameter spaces are discussed, and connections with string theory are revealed. Assumes a graduate level understanding of real and complex analysis, and fluid mechanics.

Our knowledge of objects of complex and potential analysis has been enhanced recently by ideas and constructions of theoretical and mathematical physics, such as quantum field theory, nonlinear hydrodynamics, material science. These are some of the themes of this refereed collection of papers, which grew out of the first conference of the European Science Foundation Networking Programme 'Harmonic and Complex Analysis and Applications' held in Norway 2007.
