Topic Proposal Higher Ramification Groups
2.1 Preliminaries Let K be a field, complete under discrete valuation vK with valuation ring AK and maximal ideal pK . Let K̄ be the residue field of K, assume that it is perfect. UK denotes the multiplicative group of invertible elements of AK . For a finite separable extension L of K, define vL, AL, pL, L̄ and UL in a similar manner. We assume that L̄|K̄ is separable. Let e = eL|K and f = fL|K be...
متن کاملRank one phenomena for mapping class groups
Let Σg be a closed, orientable, connected surface of genus g ≥ 1. The mapping class group Mod(Σg) is the group Homeo(Σg)/Homeo0(Σg) of isotopy classes of orientation-preserving homeomorphisms of Σg. It has been a recurring theme to compare the group Mod(Σg) and its action on the Teichmüller space T (Σg) to lattices in simple Lie groups and their actions on the associated symmetric spaces. Indee...
متن کاملValue Monoids of Zero-dimensional Valuations of Rank One
Classically, Gröbner bases are computed by first prescribing a fixed monomial order. Moss Sweedler suggested an alternative in the mid 1980s and developed a framework to perform such computations by using valuation rings in place of monomial orders. We build on these ideas by providing a class of valuations on K(x, y) that are suitable for this framework. We then perform such computations for i...
متن کاملRank one discrete valuations of power series fields
In this paper we study rank one discrete valuations of the field k((X1, . . . ,Xn)) whose center in k[X1, . . . ,Xn] is the maximal ideal. In sections 2 to 6 we give a construction of a system of parametric equations describing such valuations. This amounts to finding a parameter and a field of coefficients. We devote section 2 to finding an element of value 1, that is, a parameter. The field o...
متن کاملHigher rank Einstein solvmanifolds
In this paper we study the structure of standard Einstein solvmanifolds of arbitrary rank. Also the validity of a variational method for finding standard Einstein solvmanifolds is proved.
