Gradings Allowing wild Automorphisms
نویسندگان
چکیده
In 2004, Shestakov and Umirbaev proved that the Nagata automorphism of polynomial algebra in three variables is wild. We fix a [Formula: see text]-grading on this consider graded-wild automorphisms, i.e. such automorphisms cannot be decomposed onto elementary respecting grading. describe all gradings allowing automorphisms.

Wild monodromy and automorphisms of curves
Let R be a complete discrete valuation ring of mixed characteristic (0, p) with field of fractions K containing the p-th roots of unity. This paper is concerned with semi-stable models of p-cyclic covers of the projective line C −→ PK . We start by providing a new construction of a semi-stable model of C in the case of an equidistant branch locus. If the cover is given by the Kummer equation Zp...
متن کاملRamification of Wild Automorphisms of Laurent Series Fields
We study the structure of the Nottingham group N (Fp) of power series f ∈ X · Fp[[X]] with f (0) = 1 where p > 2 is prime, which is isomorphic to the group of wild automorphisms of Fp((X)). We concern ourselves with power series g ∈ N (Fp) with g 6= X for all m ≥ 1 (that is, power series of infinite order in N (Fp)), and we determine a necessary and sufficient criterion for such g ∈ N (Fp) havi...
متن کاملUniversal Gradings of Orders
An order is a commutative ring of which the additive group is a finitely generated free abelian group, and a graded order is an order that is provided with a grading by some abelian group. Examples are provided by group rings of finite abelian groups over rings of integers in number fields. We generalize known properties of nilpotents, idempotents, and roots of unity in such group rings to the ...
متن کاملGradings in Modular Representations
This paper considers Weyl modules for a simple, simply connected algebraic group over an algebraically closed field k of positive characteristic p. The main result proves that Weyl modules have (cogood) p-filtrations subject to restrictions on p. In case the high weight of the Weyl module is p-regular, the p-filtration is compatible with theG1-radical series of the module. This is a preliminary...
متن کاملAdditional Gradings in Khovanov homology
The main goal of the present paper is to construct new invariants of knots with additional structure by adding new gradings to the Khovanov complex. The ideas given below work in the case of virtual knots, closed braids and some other cases of knots with additional structure. The source of our additional grading may be topological or combinatorial; it is axiomatised for many partial cases. As a...
