The orientation preserving topological symmetry group of
a graph embedded in the 3-sphere is the subgroup of the automorphism
group of the graph consisting of those automorphisms which can be
induc...

Let R1, R2 . . . Rm be rotations generating SOd+1, d ≥
2, and f1, f2 . . . fm be their small smooth perturbations. We show
that {fα} can be simultaneously linearized if and only if the assocated ran...

2014/12/20
We show that one-dimensional topological objects (kinks) are natural degrees of freedom for an antiferromagnetic Ising model on a triangular lattice. Its ground states and the coexistence of spin orde...
Mesophases of soft-sphere aggregates
The soft ball interaction attractive aggregation
font style='font-size:12px;'>
2014/12/19
Soft spheres interacting via a hard core and a range of attractive and repulsive ‘soft-shoulder’ potentials self-assemble into clusters forming a variety of mesophases. We combine a mean-field theory ...

2014/12/18
A new algorithm is presented for the solution
of the shallow water equations on quasi-uniform spherical
grids. It combines a mimetic finite volume spatial discretization with a Crank–Nicolson ...
