SOME EXAMPLES OF DR-INDECOMPOSABLE CLOSED FIBERS OF SEMI-STABLE REDUCTIONS OVER WITT RINGS

For instance, we solve the homotopy limit problem for Dedekind rings whose fraction field is a number field, calculate the various flavours of Grothendieck-Witt groups ofℤ, show

Uniqueness of ρ-quasiregular approaching neighborhood In this section, we prove that two ρ-quasiregular approaching semi-algebraic neighborhoods of a closed non-compact

The idea to obtain Kahler-Einstein metrics on a projective complex variety as a limit of Fubini-Study.. metrics is due to Yau and Tian ([Y2]

Let K be a complete discrete valuation field with integer ring OK and residue..

Here (M, g) is a compact indecomposable Lorentzian 3-manifold which is not, up to a possible 2- cover, a flat torus, endowed with a lightlike parallel vector field X whose closure

It is also shown that each indecomposable injective module over local Noetherian rings of Krull dimension one has finite Malcev rank.. The preservation of the finiteness of

It is proven that the weak dimension of each FP-injective module over a chain ring which is either Archimedean or not semicoherent is less or equal to 2.. This implies that

— There is no exchange ring (thus, no von Neumann regular ring and no C*-algebra of real rank zero) with finite stable rank whose semilattice of finitely generated,
