Bloch–Srinivas conjecture on the stabilisation of relative KK-theory filtrations

At least 11 years old · documented by

Let X′→XX'\to X be a desingularisation of an integral variety XX, with exceptional fibre E↪X′E\hookrightarrow X'. For a positive integer nn, let FdK0(X′,nE)F^dK_0(X',nE) denote the codimension-dd part of the KK-theory of X′X' relative to the thickening nEnE, and let FdK0(X)F^dK_0(X) be the corresponding filtration piece for XX. Bloch–Srinivas conjecture. The inverse system

FdK0(X′,E)⟵FdK0(X′,2E)⟵FdK0(X′,3E)⟵⋯F^dK_0(X',E)\longleftarrow F^dK_0(X',2E)\longleftarrow F^dK_0(X',3E)\longleftarrow\cdots

stabilises, with stable value FdK0(X)F^dK_0(X). This conjecture concerns the relationship between zero-cycle-type information on a singular variety and the relative KK-theory of a desingularisation along its exceptional fibre; the supplied text does not state whether it has been resolved.
