Research Abstract

We proved a mixed version of SL (2)-orbit theorem. We constructed mixed versions of Borel-Serre compactifications, spaces of SL (2)-orbits, and spaces of nilpotent orbits, and obtained their fundamental diagram. Now the foundation of log mixed Hodge theory is almost established. The relationship between these results and geometry and physics, such as Hodge conjecture, mirror symmetry, etc., is gradually watched.
