DESCRIPTION: Abstract: We continue from last week by defining K_0 and K
_1-regularity of a ring and prove that a regular ring is K_0 and K_1-regula
r. We show that distinguished squares of schemes give rise to an exact sequ
ence relating their Picard groups and prove that K_0-regularity implies Pic
-regularity. Then we define the Karoubi-Villamayor K-theory groups of a rin
g and relate these to the K_0 and K_1 groups. Further details: http://us
