Brauer groups and Néron class groups [PDF]

open access: yesInternational Journal of Number Theory, 2020
Let [Formula: see text] be a global field and let [Formula: see text] be a finite set of primes of [Formula: see text] containing the Archimedean primes. We generalize the duality theorem for the Néron [Formula: see text]-class group of an abelian variety [Formula: see text] over [Formula: see text] established previously by removing the requirement ...

Brauer Analysis of Thompson’s Group F and Its Application to the Solutions of Some Yang–Baxter Equations

open access: yesMathematics
The study of algebraic invariants associated with Brauer configuration algebras induced by appropriate multisets is said to be a Brauer analysis of the data that define the multisets.

The genus of a division algebra and the unramified Brauer group [PDF]

open access: yes, 2013
Let $$D$$ be a finite-dimensional central division algebra over a field $$K$$. We define the genus $$\mathbf{gen}(D)$$ of $$D$$ to be the collection of classes $$[D^{\prime }] \in \mathrm{Br}(K)$$, where $$D^{\prime }$$ is a central division $$K ...

Comparing descent obstruction and Brauer-Manin obstruction for open varieties

open access: yes, 2018
We provide a relation between Brauer-Manin obstruction and descent obstruction for torsors over open varieties under a connected linear algebraic group or a group of multiplicative type is given.

The unramified Brauer group of norm one tori [PDF]

open access: yes, 2012
Let k be a number field and K/k Galois. We transform the construction of the unramified Brauer group of the norm one torus RK/k1(Gm) into the construction of a special abelian extension over K.

Cost Pass‐Through in Crisis: Evidence From the German Malt‐Beer Supply Chain

open access: yesAgribusiness, EarlyView.
Abstract Global agri‐food supply chains are increasingly exposed to geopolitical shocks, climate volatility, and market consolidation, factors that disrupt traditional price relationships and reshape market power dynamics. Nowhere is this more visible than in the brewing sector, where agricultural raw materials meet complex industrial processing and ...

Existence of Pseudo-Superinvolutions of the First Kind

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
Our main purpose is to develop the theory of existence of pseudo-superinvolutions of the first kind on finite dimensional central simple associative superalgebras over 𝐾, where 𝐾 is a field of characteristic not 2.
