Stable connectivity over a base
Abstract
Morel's stable connectivity theorems state that for any connective -spectrum of motivic spaces (Nisnevich simplicial sheaves) over an arbitrary field, the spectrum is connective, and the same property for -spectra of motivic spaces. Here denotes the -localisation in the category of motivic spectra over a field . Originally the same property was conjectured for the case of motivic -spectra over a base scheme .In view of Ayoub's conterexamples the modified version of conjecture states that is -connective for any connective , where is the Krull dimension. The conjecture is proven under the infiniteness assumption on the residue fields for the cases of Dedekind schemes by J.~Schmidt and F.~Strunk and noetherian domains of arbitrary dimension by N.~Deshmukh, A.~Hogadi, G.~Kulkarni and S.~Yadavand. In the article we prove the result or general base with out the assumption on the residue fields. So by the result for any smooth scheme over a base scheme of Krull dimension the Nisnevich sheaves of -stable motivic homotopy groups and -stable motivic homotopy groups vanishes for all .
