Cohomological invariants of algebraic tori

Alexander Merkurjev (UCLA - Personal website)

A cohomological invariant of an algebraic group G defined over a field F with values in a Galois module C is a morphism of functors H^1(-,G) --> H^d(-,C) from the category of field extensions of F to the category of pointed sets. Cohomological invariants of algebraic tori and their applications will be discussed. (This is joint work with S. Blinstein, UCLA.)
