The Federico Santa María Technical University in Valparaíso, Chile, will be hosting the 9th international conference on Computational Methods and Function Theory (CMFT 2021) to be held January 10-14, 2022. The conference will be held in memory of Stephan Ruscheweyh, who initiated the series of CMFT conferences and has been the driving force behind all the previous conferences. The general theme of the meeting concerns various aspects of interaction of complex variables and scientific computation, including related topics from function theory, holomorphic function spaces, approximation theory and numerical analysis. Another important aspect of the CMFT meetings, previously held in Valparaíso 1989, Penang 1994, Nicosia 1997, Aveiro 2001, Joensuu 2005, Ankara 2009, Shantou 2013, and Lublin 2017, is to promote the creation and maintenance of contacts with scientists from diverse cultures.
