Norms in finite galois extensions of the rationals

International Journal of Mathematics and Mathematical Sciences, 1990
We show that under certain conditions a rational number is a norm in a given finite Galois extension of the rationals if and only if this number is a local norm at a certain finite number of places in a certain finite abelian extension of the rationals.

Ternary SU(3)-group symmetry and its possible applications in hadron-quark substructure. Towards a new spinor-fermion structure [PDF]

EPJ Web of Conferences, 2019
The questions on the existence of the three color quark symmetry and three quark-lepton generations could have the origin associated with the new exotic symmetries outside the Cartan-Killing-Lie algebras/groups.

Combinable Extensions of Abelian Groups [PDF]

, 2009
The design of decision procedures for combinations of theories sharing some arithmetic fragment is a challenging problem in verification. One possible solution is to apply a combination method à la Nelson-Oppen, like the one developed by Ghilardi for unions of non-disjoint theories.

Extended Genus Fields of Abelian Extensions of Rational Function Fields

Axioms
In this paper, we obtain the extended genus field of a finite abelian extension of a global rational function field. We first study the case of a cyclic extension of prime power degree. For the general case, we use the fact that the extended genus fields

A toy model for background independent string field theory

Journal of High Energy Physics, 2022
We study gauge theories of background fields associated to BRST quantized spinning particle models and identify background-independent algebraic structures which allow to systematically reduce the spectrum of fields and subject some of them to dynamical ...

Renormalizable extension of the Abelian Higgs-Kibble model with a dim.6 derivative operator

SciPost Physics Proceedings, 2023
We present a new approach to the consistent subtraction of a non power-counting renormalizable extension of the Abelian Higgs-Kibble (HK) model supplemented by a dim. 6 derivative-dependent operator controlled by the parameter $z$.

Compact Manifolds With Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has a uniformly almost nilpotent fundamental group. Leftover questions and conjectures, have asked if in this context the fundamental group is actually uniformly almost abelian. The main goal of this work is to construct examples (Mk9,gk)$(

Finite 2-groups whose the same-order type is arithmetic progressions [PDF]

European Journal of Mathematics and Applications
The same-order type $\tau_e(G)$ of a finite group $G$ is a set formed from the sizes of the equivalence classes containing elements of the same order in $G$.
