Operator Theory and Its Applications: In Memory of V. B. Lidskii (1924-2008)

This book is a collection of articles devoted to the theory of linear operators in Hilbert spaces and its applications. The subjects covered range from the abstract theory of Toeplitz operators to the analysis of very specific differential operators arising in quantum mechanics, electromagnetism, and the theory of elasticity; the stability of numerical methods is also discussed. Many of the articles deal with spectral problems for not necessarily selfadjoint operators. Some of the articles are surveys outlining the current state of the subject and presenting open problems.

Social development: bridging the theory-practice divide, past and present

Introduces a collection of articles appearing in a special issue that reflect on social development, considering the various intellectual forms social development has taken, how development thinking has been shaped by different concepts in different periods, and how contributors' personal experiences with social development research has been applied to social development practice.
