- Gave solution of the threeWeil conjecturesconcerning generalizations of theRiemann hypothesisto finite fields. His work did much to unifyalgebraic geometryandalgebraic number theory.
- Contributed several innovations that revised the study of multidimensionalcomplex analysisby finding correct generalizations of classical (low-dimensional) results.
- Provided innovative analysis of the structure ofLie groups. His work belongs tocombinatorics,differential geometry,ergodic theory,dynamical systems, and Lie groups.
