This Special Issue focuses on recent advances in density functional theory. Though 50 years have passed since the formulation of Kohn‐Sham density functional theory, many open questions remain. Some of the topics in this Special Issue include open mathematical questions, the development of more accurate density functionals, the development of accurate kinetic energy functionals, and applying density functional theory to solve new and exciting scientific problems. The Special Issue features the highlights of the 16th International Conference on Density Functional Theory and its Applications held in Debrecen, Hungary, August 31 – September 4, 2015.
