(Elsevier Masson SAS, 2011-03)Formulae for the levels and sublevels of certain quaternion and octonion algebras are established. Corollaries concerning the equality of levels and sublevels of quaternion algebras with those of associated octonion algebras ...
-
(Royal Irish Academy, 2010)Certain families of quaternion and octonion algebras are conjectured to be of level and sublevel n. A proof of this conjecture is offered in the case where n is a power of two. Hoffmann's proof of the existence of infinitely ...
-
(Elsevier, 2007)Lewis' and Leep's bounds on the level and sublevel of quaternion algebras are extended to the class of composition algebras. Some simple constructions of composition algebras of known level values are given. In addition, ...
-
(Birkhäuser, 2008)In [O'S], the level and sublevel of composition algebras are studied, wherein these quantities are determined for those algebras defined over local fields. In this paper, the level and sublevel of composition algebras, of ...

(Elsevier, 2010-07)In 1976 Procesi and Schacher developed an Artin–Schreier type theory for central simple algebras with involution and conjectured that in such an algebra a totally positive element is always a sum of hermitian squares. In ...

(Elsevier, 2012-07-01)The question of which quadratic forms become isotropic when extended to the function field of a given form is studied. A formula for the minimum dimension of the minimal isotropic forms associated to such extensions is ...
-
(Elsevier, 1997-07)The paper describes the use of algebraic linear programming for the minimum weight design of steel portal frames subject to the constraints of the Kinematic Theorem of plastic collapse. Minimum weight design is a classic ...

(Elsevier Science, 1989-02)When the information of an agent is represented as a sigma algebra on a probability space, iterative public announcement of an aggregate statistic on posteriors leads to convergence of each agent's posterior distribution ...

(University College Dublin. School of Economics, 2000-12-11)I take the publication of The Spatial Economy by Fujita, Krugman and Venables as an opportunity to expound and assess the "new economic geography". I use a simple diagram to show how the basic model works; give a ...
