Geometric Structures in Group Theory
Oberwolfach Reports, 2014 The general subject of the conference was geometric group theory, that is the study of groups via suitable actions on spaces endowed with additional structures, for instance a distance, a measure (class), or both of them with natural compatibilities. The interactions with other mathematical fields such as algebraic topology (e.g.

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

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 ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows
Advanced Engineering Materials, EarlyView.A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

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 ...

Twisted compactifications of 3d N $$ \mathcal{N} $$ = 4 theories and conformal blocks
Journal of High Energy Physics, 2019 Three-dimensional N $$ \mathcal{N} $$ = 4 supersymmetric quantum field theories admit two topological twists, the Rozansky-Witten twist and its mirror.

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.

Holographic duals of 3d S-fold CFTs
Journal of High Energy Physics, 2018 We construct non-geometric AdS4 solutions of IIB string theory where the fields in overlapping patches are glued by elements of the S-duality group. We obtain them by suitable quotients of compact and non-compact geometric solutions.
