Braided finite automata and representation theory
We introduce classical and non-deterministic finite automata associated with representations of the braid group. After briefly reviewing basic definitions on finite automata, Coxeter’s groups and the associated word problem, we turn to the Artin ...

CLASSIFICATION OF SYMMETRY GROUPS FOR PLANAR $n$ -BODY CHOREOGRAPHIES
Since the foundational work of Chenciner and Montgomery in 2000 there has been a great deal of interest in choreographic solutions of the $n$ -body problem ...

Quasi-morphisms on the group of area-preserving diffeomorphisms of the $2$-disk via braid groups
Recently Gambaudo and Ghys proved that there exist infinitely many quasi-morphisms on the group 𝐷𝑖𝑓𝑓_{Ω}^{∞}(𝐷²,∂𝐷²) of area-preserving diffeomorphisms of the 2-disk 𝐷².

ON WORD REVERSING IN BRAID GROUPS [PDF]
It has been conjectured that in a braid group, or more generally in a Garside group, applying any sequence of monotone equivalences and word reversings can increase the length of a word by at most a linear factor depending on the group presentation only.

The study of literature and art is not a sociological one, as some might think. Both are a phenomenon of human social phenomena whose existence and development are linked to the development of culture.

Flow diverter braid deformation is occasionally observed after flow diverter placement. However, the frequency and clinical significance of flow diverter braid deformation in non-drawn filled tube wire devices remain unclear.

Unusual Mathematical Approaches Untangle Nervous Dynamics
The massive amount of available neurodata suggests the existence of a mathematical backbone underlying neuronal oscillatory activities. For example, geometric constraints are powerful enough to define cellular distribution and drive the embryonal ...
