该研究受Ischebeck的代数K理论次整扩张工作启发,在埃尔米特K理论中证明零次格罗滕迪克-维特群在次整扩张下不变,并建立了多项式环几何子环上大维特指数二次空间的消去定理。
AI 中文摘要
受Ischebeck关于代数K理论函子在次整扩张下性态研究的启发,我们研究埃尔米特K理论中的类似问题。我们证明了零次格罗滕迪克-维特群在次整扩张下具有不变性,还研究了多项式环几何子环上二次空间的消去问题,建立了具有足够大维特指数的二次空间的消去定理。
英文摘要
Motivated by the work of Ischebeck on the behaviour of algebraic $K$-theoretic functors under subintegral extensions, we investigate the analogous question in Hermitian $K$-theory. We prove that Grothendieck-Witt groups in degree zero are invariant under subintegral extensions. We also investigate the cancellation problem for quadratic spaces over geometric subrings of polynomial rings and establish a cancellation theorem for quadratic spaces of sufficiently large Witt index.
