General Geometrical Models of Grain Boundaries
Geonetric models of grain boundaries have been extensively studied following Bollmann's original ideas. 1hese models apply only for symmorphic structures with one atom per primitive unit cell. These restrictions may be easily avoided by introducing some elementary concepts of crystallography which lead to an unified description of homophase interfaces. Ihe notion of symmetry dictated extrema is...
متن کاملGeometrical properties of parafermionic spin models
We present measurements of the fractal dimensions associated to the spin clusters for Z4 and Z5 spin models. We also attempted to measure similar fractal dimensions for the generalised Fortuin Kastelyn (FK) clusters in these models but we discovered that these clusters do not percolate at the critical point of the model under consideration. These results clearly mark a difference in the behavio...
متن کاملSome geometrical properties of the oscillator group
We consider the oscillator group equipped with a biinvariant Lorentzian metric. Some geometrical properties of this space and the harmonicity properties of left-invariant vector fields on this space are determined. In some cases, all these vector fields are critical points for the energy functional restricted to vector fields. Left-invariant vector fields defining harmonic maps are...

متن کاملAsymptotic properties of free monoid morphisms
Motivated by applications in the theory of numeration systems and recognizable sets of integers, this paper deals with morphic words when erasing morphisms are taken into account. Cobham showed that if an infinite word w = g(f(a)) is the image of a fixed point of a morphism f under another morphism g, then there exist a non-erasing morphism σ and a coding τ such that w = τ (σ(b)). Based on the ...
