The Witt group of a scheme is a globalization to schemes of the classical Witt group of a field. It is a part of a cohomology theory for schemes
called the derived Witt groups. In this talk, we introduce two problems about the derived Witt groups, the Gersten conjecture and a
finite generation question for arithmetic schemes, and explain recent progress on them.
