备注
In this version (March 2018) there are new sections with extra results about the extension problem in SL(n). In version 3 add two sections 8 and 9 concerning the extension problem for affine quadrics and SL (n). The first seven sections are essentially the same. In version 4 there are small corrections in Proposition 6.7 and Remark 6.8
