Unramified cohomology of quadrics in characteristic two

چکیده
Let $F$ be a field of characteristic 2 and let $X$ smooth projective quadric dimension $\ge 1$ over $F$. We study the unramified cohomology groups with 2-primary torsion coefficients in degrees 3. determine completely kernel cokernel natural map from to $X$. This extends results different obtained by Kahn, Rost Sujatha nineteen-nineties.

Unramified Cohomology of Quadrics, Iii
This paper is the third and last instalment of our project of computation of the low-degree unramified cohomology of quadrics. As in the previous papers [15] and [16], we denote by η X the map H(F,Q/Z(n− 1))→ H nr(F (X)/F,Q/Z(n− 1)) for a smooth, projective quadric X defined over a field F of characteristic 6= 2. Recall that in these papers we proved that Ker η X is generated by symbols for n ≤...
متن کاملUnramified Cohomology of Quadrics, Ii
We compute the unramified cohomology of quadrics of dimension 4 in degree 4 over an arbitrary field of characteristic different from 2. We find that it is related to classical invariants of a more elementary nature, such as the group of spinor norms and the projective special orthogonal group modulo Manin’s R-equivalence.

We construct and study universal spaces for birational invariants of algebraic varieties over algebraic closures of finite fields.
متن کاملBirational geometry of quadrics in characteristic 2
The theory of quadratic forms can be regarded as studying an important special case of the general problem of birational classification of algebraic varieties. A typical example of a Fano fibration in minimal model theory is a quadric bundle, which can be viewed without loss of information as a quadric hypersurface over the function field of the base variety. This description feeds the problem ...
متن کاملUnramified Skolem Problems and Unramified Arithmetic Bertini Theorems in Positive Characteristic
In this paper, we prove unramified, positive-characteristic versions of theorems of Rumely and Moret-Bailly that generalized Skolem’s classical problems, and unramified, positive-characteristic versions of arithmetic Bertini theorems. We also give several applications of these results. 2000 Mathematics Subject Classification: Primary 11G35; Secondary 11G25, 14G15, 14G25, 14H25
