Ramification Theory for Local Field with Imperfect Residue Field
Definition 1.3. The most natural way to define higher ramification subgroups of the Galois group G is due by Hilbert: g ∈ Ga if and only if vl(gx− x) ≥ a + 1, ∀x ∈ Ol. Indeed, G−1 = G, G0 = I is the inertia subgroup, and G1 = W is the wild inertia subgroup. However, there is a disadvantage of this. Namely, it does not respect quotient and hence it does not give a filtration on the absolute Galo...

متن کاملLocal Casimir energy for solitons
A direct calculation of the one-loop contributions to the energy density of bosonic and supersymmetric φ4 kinks exhibits: (1) Local mode regularization. Regularization of the Casimir energy density maintains equality for the soliton and trivial vacua of not only the total number of field oscillation modes, but also the total mode density at each point in space. This yields the anomalous part of...
متن کاملLocal Cohomology in Field Theory
This is an introductory survey of the theory of p-form conservation laws in field theory. It is based upon a series of lectures given at the Second Mexican School on Gravitation and In these lectures I will provide a survey of some aspects of the theory of local coho-mology in field theory and provide some illustrative applications, primarily taken from the Einstein equations of the general the...
متن کاملD-branes as GMS Solitons in Vacuum String Field Theory
In this paper we map the D-brane projector states in the vacuum string field theory to the noncommutative GMS solitons based on the recently proposed map of Witten’s star to Moyal’s star. After properly regularizing the mid-point singularity of the sliver states in the Moyal basis, we reproduce the singular geometry conditions of Moore and Taylor in our framework. The properties of the candidat...
