Thoracoscopic division of vascular rings
Journal of Pediatric Surgery, 2017Vascular rings are traditionally treated via an open thoracotomy. In recent years the use of thoracoscopy has increased. Herein we report our experience with thoracoscopic division of vascular rings in pediatric patients.We reviewed all patients who underwent thoracoscopic or open division of a vascular ring at our institution between 2007 and 2015. We

Group Rings and Division Rings
1984Continuing the work in [ll],[l2] we study division algebras D = k(G) over a field k which are generated by some polycyclic-by-finite subgroup G of the multiplicative group D* of D. We discuss a specific class of examples of such division algebras that can be thought of as multiplicative analogs of the Weyl field.

A V-ring is a ring for which every simple right module is injective. If D is a division algebra over a field k, then an \(n\times n\) matrix A over D is called totally transcendental over k if f(A) is invertible for every non-zero polynomial f over k.

The study of quantum polynomial rings was initiated by J. C. McConnell and J. J. Pettit [MP] as multiplicative analog of the Weyl algebra. They are of considerable interest in non-commutative algebraic geometry.

On Conjugates in Division Rings
Canadian Journal of Mathematics, 1958Let D be a non-commutative division ring with centre C, and let Δ be a proper division subring not contained in C. In (4) Cartan raised the question: is it ever possible for each inner automorphism of D to induce an automorphism of Δ? As is well-known, Cartan (4, Théorème 4) with the aid of his Galois Theory answered this negatively in case D is a ...
