Journal of Pure and Applied Algebra, 1995 Let \(D\) be a division ring with involution *, center \(F\) and \([D : F] < \infty \). Since furthermore \(D\) is required to have a weak *-ordering, only the following two cases occur: (1) \((D,*)\) is a standard quaternion-algebra or (2) \([D : F]\) is odd.

Proceedings of the American Mathematical Society, 1952 In this paper we shall give a necessary and sufficient condition that a skew field can be ordered; moreover, that the ordering of an ordered skew field K can be extended to an ordering of L, L being a given extension of K. The first of these two results generalizes to skew fields a theorem of E. Artin and 0.

Proceedings of the Japan Academy, Series A, Mathematical Sciences, 1993 In Part I [ibid. 69, 45-48 (1993; Zbl 0795.11056)], the author gave a criterion for an arbitrary order to have class group generated by ambiguous ideals and also made a conjecture related to that criterion. Afterwards, however, counterexamples to the conjecture were found [cf. Part III, ibid. 70, 176-181 (1994; Zbl 0809.11064)].

Effective impedance over ordered fields [PDF]
Journal of Mathematical Physics, 2021 In this paper, we study the properties of effective impedances of finite electrical networks, considering them as weighted graphs over an ordered field. We prove that a star-mesh transform of finite network does not change its effective impedance. Moreover, we consider two particular examples of infinite ladder networks (Feynman’s network or LC-network

, 2015 For $n=3$, 4, and 5, we prove that, when $S_n$-number fields of degree $n$ are ordered by their absolute discriminants, the lattice shapes of the rings of integers in these fields become equidistributed in the space of lattices.Comment: 12 ...

Hermitian Forms over Ordered ∗ -Fields
Journal of Algebra, 1999 Let \((D,{}^*)\) be a skew field with an involution *. Let \(Y_D\) and \(X_D\) denote space of Baer orderings and its subspace of *-orderings on \((D,{}^*).\) The main object of interest of the paper is the subring \(WS(D,{}^*)\) of the ring \({\mathcal C}(Y_D,Z)\) of continuous functions from \(Y_D\) to the ring of integers generated by the image of ...

The Two-Dimensional Square-Lattice S=1/2 Antiferromagnet Cu(pz)$_2$(ClO$_4$)$_2$
, 2010 We present an experimental study of the two-dimensional S=1/2 square-lattice antiferromagnet Cu(pz)$_2$(ClO$_4$)$_2$ (pz denotes pyrazine - $C_4H_4N_2$) using specific heat measurements, neutron diffraction and cold-neutron spectroscopy.
