Quadratic Forms, Linear Algebraic Groups, and Cohomology

The invited papers collected in this volume address topics related to the research of Raman Parimala (plenary speaker at the upcoming ICM 2010). These themes focus primarily on the interplay between algebra, number theory, and algebraic geometry. The included contributions cover exciting research in areas such as field patching and a proof of the Serre`s Conjecture II for function fields of complex surfaces.
