Abstract

The purpose of this note is to show that, in contrast to the Fp{\Bbb F}_p-case (proven in [7]), the pp-primary and pp-adic cases of the Isotropy Conjecture, claiming that the isotropic Chow groups with Z/pr{\Bbb Z}/p^r, r>1r>1, respectively, with Zp{\Bbb Z}_p-coefficients over a flexible field coincide with the numerical ones, don't hold. We show that the BPBP-theory with I()I(\infty)-primary, respectively, I()I(\infty)-adic coefficients may serve as a regular substitute for pp-primary, respectively, pp-adic Chow groups, which permits to extend the results of [6] to arbitrary primes.
