设A是一个noether fp -代数,它被有限地生成为子Ap (p次幂)的模。我们给出了幂级数环A[[t]]的de Rham-Witt复形与环A的复形的显式公式。我们利用这个公式证明了,对于每一个残馀域是p次幂子域的有限扩展的完备正则局部fp -代数,从具有Z/pv系数的代数k理论到具有Z/pv系数的拓扑k理论的正则映射是同构的。
Let A be a noetherian Fp-algebra that is finitely generated as a module over the subring Ap of pth powers. We give an explicit formula for the de Rham-Witt complex of the power series ring A[[t]] in terms of that of the ring A. We use this formula to show that, for every complete regular local Fp-algebra whose residue field is a finite extension of the subfield of pth powers, the canonical map from the algebraic K-theory with Z/pv-coefficients to the topological K-theory with Z/pv-coefficients is an isomorphism.
