This book presents the proceedings of the 20th International Workshop on Hermitian Symmetric Spaces and Submanifolds, which
was held at the Kyungpook National University from June 21 to 25, 2016. The Workshop was supported by the Research Institute
of Real and Complex Manifolds (RIRCM) and the National Research Foundation of Korea (NRF). The Organizing Committee invited
30 active geometers of differential geometry and related fields from all around the globe to discuss new developments for
research in the area. These proceedings provide a detailed overview of recent topics in the field of real and complex submanifolds.
