Supersymmetric RG flows and Janus from type II orbifold compactification
European Physical Journal C: Particles and Fields, 2017 We study holographic RG flow solutions within four-dimensional $$N=4$$ N = 4 gauged supergravity obtained from type IIA and IIB string theories compactified on $$T^6/\mathbb {Z}_2\times \mathbb {Z}_2$$ T 6 / Z 2 × Z 2 orbifold with gauge, geometric and ...

Kähler groups and Geometric Group Theory
, 2017 In this thesis we study Kähler groups and their connections to Geometric Group Theory. This work presents substantial progress on three central questions in the field: Which subgroups of direct products of surface groups are Kähler? Which Kähler groups admit a classifying space with finite (n-1)-skeleton but no classifying space with finitely many n ...

Advanced Engineering Materials, EarlyView.Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Advanced Engineering Materials, EarlyView.Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization
Advanced Engineering Materials, EarlyView.Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Foundations of geometric approximate group theory [PDF]
We develop the foundations of a geometric theory of countably-infinite approximate groups, extending work of Björklund and the second-named author. Our theory is based on the notion of a quasi-isometric quasi-action (qiqac) of an approximate group on a ...

Introducción a la teoría geométrica de grupos
Revista Integración, 2011 En este artículo haremos una introducción a la teoría geométrica de grupos. Veremos cómo a partir de una presentación finita de un grupo, se puede dotar a dicho grupo de una estructura de espacio métrico; se discute la acción del grupo sobre dicho ...

Geometric Group Theory. Groups arise naturally as symmetries of geometric objects. Often groups have an interesting geometric structure obtained by thinking of these geometric objects coursely.
