%0 Journal Article %T Higher algebraic K-theory and tangent spaces to Chow groups %A Sen Yang %J Mathematics %D 2013 %I arXiv %X This is a reproduction of my thesis. By using higher K-theory(Chern character, cyclic homology, effacement theorem and etc), we provide an answer to a question by Green- Griffiths which says the tangent sequence to Bloch-Gersten-Quillen sequence is Cousin resolution. %U http://arxiv.org/abs/1310.6773v1
