Ramification Theory for Higher Dimensional Local Fields
The paper contains a construction of ramification theory for higher dimensional local fields K provided with additional structure given by an increasing sequence of their “subfields of i-dimensional constants”, where 0 i n and n is the dimension of K. It is also announced that a local analogue of the Grothendieck Conjecture still holds: all automorphisms of the absolute Galois group of K, which...
متن کاملExistence theorem for higher local fields
A field K is called an n-dimensional local field if there is a sequence of fields kn, . . . , k0 satisfying the following conditions: k0 is a finite field, ki is a complete discrete valuation field with residue field ki−1 for i = 1, . . . , n, and kn = K . In [9] we defined a canonical homomorphism from the n th Milnor group Kn(K) (cf. [14]) of an n-dimensional local field K to the Galois group...
متن کاملHigher dimensional local fields Igor
Suppose that we are given a surface S over a finite field of characteristic p, a curve C ⊂ S , and a point x ∈ C such that both S and C are regular at x. Then one can attach to these data the quotient field of the completion ̂ (ÔS,x)C of the localization at C of the completion ÔS,x of the local ring OS,x of S at x. This is a two-dimensional local field over a finite field, i.e., a complete discr...
متن کاملHigher dimensional local fields and L - functions
Example. Let X be an algebraic projective irreducible surface over a field k and let P be a closed point of X , C ⊂ X be an irreducible curve such that P ∈ C . If X and C are smooth at P , then we let t ∈ OX,P be a local equation of C at P and u ∈ OX,P be such that u|C ∈ OC,P is a local parameter at P . Denote by C the ideal defining the curve C near P . Now we can introduce a two-dimensional l...
