Pure Maths Colloquium: Biextensions of Algebraic Cycles

Presented by James Lewis, University of Alberta (Canada)

23 February 2009 16:15 in CM 107

Let X be a smooth complex projective variety. We provide a description of a biextension and archimedean height pairing of two cycles whose classes belong to a certain Bloch-Beilinson filtration level in the Chow group of $X$.
