In this context, a regulator is a map from the algebraic K-theory of an algebraic variety to a suitable cohomology theory such as étale cohomology or Deligne cohomology. The 16 papers, selected from 35 presentations, include discussions of primitive cycles and the Fourier-Radon transform, the derivative of a normal function associated with a Deligne cohomology class, secondary theories for étale groupiods, finite generation conjectures for motivic cohomology theories over finite fields, and derived categories of coherent sheaves and motives of K3 surfaces. Two of the papers are in French. There is no index. Annotation ©2012 Book News, Inc., Portland, OR (booknews.com)
