Un'osservazione sulle classi di Fitting normali
We prove that a Fitting class of finite soluble groups is normal if and only if it verifies the condition ) (see n. 2). Unlike the definition of normal Fitting class, this condition is “constructive”.
Unramified cohomology of alternating groups
We prove vanishing results for the unramified stable cohomology of alternating groups.
Unramified cohomology of classifying varieties for classical simply connected groups
Unrefined minimal K-types for p-adic groups.
Unstable homotopy invariance for finite fields
We prove that if k is a finite field with elements, then the natural map is an isomorphism for 0 ≤ i < d(p-1) and for all n.
