The ISAAC Group in Pseudo-Differential Operators (IGPDO) met at the Fifth ISAAC Congress held at Universita di Catania in Italy in July, 2005. This volume consists of papers based on lectures given at the special session on pseudodifferential operators and invited papers that bear on the themes of IGPDO. Nineteen peer-reviewed papers represent modern trends in pseudo-differential operators. Diverse topics related to pseudo-differential operators are covered.

This volume consists of eighteen peer-reviewed papers related to lectures on pseudo-differential operators presented at the meeting of the ISAAC Group in Pseudo-Differential Operators (IGPDO) held at Imperial College London on July 13-18, 2009. Featured in this volume are the analysis, applications and computations of pseudo-differential operators in mathematics, physics and signal analysis. This volume is a useful complement to the volumes "Advances in Pseudo-Differential Operators", "Pseudo-Differential Operators and Related Topics", "Modern Trends in Pseudo-Differential Operators", "New Developments in Pseudo-Differential Operators" and "Pseudo-Differential Operators: Complex Analysis and Partial Differential Equations" published in the same series in, respectively, 2004, 2006, 2007, 2009 and 2010.

This volume consists of papers inspired by the special session on pseudo-differential operators at the 10th ISAAC Congress held at the University of Macau, August 3-8, 2015 and the mini-symposium on pseudo-differential operators in industries and technologies at the 8th ICIAM held at the National Convention Center in Beijing, August 10-14, 2015. The twelve papers included present cutting-edge trends in pseudo-differential operators and applications from the perspectives of Lie groups (Chapters 1-2), geometry (Chapters 3-5) and applications (Chapters 6-12). Many contributions cover applications in probability, differential equations and time-frequency analysis. A focus on the synergies of pseudo-differential operators with applications, especially real-life applications, enhances understanding of the analysis and the usefulness of these operators.

This book aims to provide first-hand information for readers who are concerned about inclusive finance and sustainable development by summarizing China’s policy measures and practical innovations in the development of inclusive finance and expects to provide China’s experience for the development of inclusive finance in more regions. From a worldwide perspective, a large number of people had been excluded from formal financial services for a long time due to various factors. Even in developed economies with sound financial systems, relatively disadvantaged groups are often denied access to effective financial services. In 2005, the United Nations proposed the concept of Inclusive Finance, emphasizing the extension of financial services to less developed regions and low-income groups in society at an affordable cost by improving financial infrastructure and providing them with reasonably priced and convenient financial services. In 2015, the United Nations adopted the 2030 Agenda for Sustainable Development, making inclusive finance an important focus for achieving sustainable development. It has become a global consensus to vigorously develop inclusive finance. China has attached importance to improving financial services for disadvantaged groups such as rural residents, micro-, small and medium enterprises (MSMEs) and others. In 2013, Developing “Inclusive Finance” became China’s national strategy. In 2015, China formulated the Plan for Promoting the Development of Inclusive Finance (2016-2020). In 2016, during its presidency of the Global Partnership for Financial Inclusion (GPFI), China proposed the issue of "Digital Financial Inclusion" and issued the G20 High-level Principles for Digital Financial Inclusion at the G20 Hangzhou Summit in the same year. Through policy guidance and active practice by the financial sector, China has gradually formed a unique development model of inclusive finance and achieved remarkable successes. Physical outlets, service machines and online service channels have been improved, and basic financial services have generally covered both urban and rural areas. The financial services for rural households and MSMEs have improved significantly. The efficiency and convenience of financial services have been significantly improved, and the satisfaction of financial services has significantly increased. China's experience in inclusive finance has been recognized by the international community. In 2017, five cases from China were selected in the G20 report on Digital Financial Inclusion: Emerging Policies and Approaches.
