This book provides some recent advance in the study of stochastic nonlinear Schrödinger equations and their numerical approximations, including the well-posedness, ergodicity, symplecticity and multi-symplecticity. It gives an accessible overview of the existence and uniqueness of invariant measures for stochastic differential equations, introduces geometric structures including symplecticity and (conformal) multi-symplecticity for nonlinear Schrödinger equations and their numerical approximations, and studies the properties and convergence errors of numerical methods for stochastic nonlinear Schrödinger equations. This book will appeal to researchers who are interested in numerical analysis, stochastic analysis, ergodic theory, partial differential equation theory, etc.

Automotive structural components are an important component that affects the performance of the entire vehicle. The light weight of automotive structural components is one of the sustainable solutions to energy and environmental issues, and the development technology of its core components and vehicle performance evaluation technology are its key development directions. To gradually replace traditional cars on a large scale, electric vehicles need to address the durability and reliability issues of the entire vehicle and key components. Prediction Methods and Evaluation of the Fatigue Life for Automotive Structural Components helps readers understand how they can do this

This new and timely book addresses a series of questions regarding one of the most important political developments in contemporary China: the state-led democratic practice of village self-government in rural areas. Why would an authoritarian state promote grassroots democratic reform? To what extent has this reform changed the local power structures, grassroots governance, and state-peasant relations? What would be the implications of this grassroots democratic reform for China's democratisation in the long run? This book examines the origins, process, and impact of this paradoxical political development and explores the dynamics of political change and mutually transforming relations between the state and society in Post-Mao China. It argues that the practice of village self-government was promoted by the Chinese party-state to cope with the dual crises of legitimacy and governability it had faced in the countryside after a decade of rural economic reforms.
