Tangent spaces to motivic cohomology groups

Abstract

BY using Green-Griffiths' results on tangent spaces to algebraic cycles [4], we study the tangent space to $C{H}^2(X,1)$, where $X$ is a nonsingular projective curve over a field $k$ of characteristic $0$.

Largely revision. For simplicity, the main example is changed from surfaces to curves
