Chern Institute of Mathematics of Nankai University (CIM, previously known as Nankai Institute of Mathematics) was founded in 1985 by the renowned mathematician Shiing-Shen Chern. Over the past 30 years, based on the mathematics department of Nankai University and supported by the Chinese mathematical community, CIM has been constantly hosting academic activities and conferences with scholars exchanging frequently, providing for communication among mathematical researchers across the world as well as being a good showcase for young scholars, and boosting the development of mathematics in China. In order to keep and promote the hosting of academic conference as a good tradition of the institute, every year CIM would collect proposals for conference from mathematical research and teaching institutions and scholars worldwide in the hope of that with the help of the platform offered by CIM, more opportunities will be provided for mathematical researchers to have academic exchanges and close cooperation, and more contribution will be made to the development of mathematics in China.
