[1101] Essential dimension

By Alexander Merkurjev

Essential dimension of an algebraic object is the smallest number of algebraically independent parameters required to define the object. This notion was introduced by J. Buhler and Z. Reichstein in 1997. The relation to different parts of algebra such as algebraic geometry, Galois cohomology and representation theory will be discussed.
