چکیده
The vortex-like solutions are studied in the framework of the gauge model of discli-nations in elastic continuum. A complete set of model equations with disclination driven dislocations taken into account is considered. Within the linear approximation an exact solution for a low-angle wedge disclination is found to be independent from the coupling constants of the theory. As a result, no additional dimensional characteristics (like the core radius of the defect) are involved. The situation changes drastically for 2π vortices where two characteristic lengths, l φ and l W , become of importance. The asymptotical behaviour of the solutions for both singular and nonsingular 2π vortices is studied.

A variant of a gauge theory is formulated to describe disclinations on Riemannian surfaces that may change both the Gaussian (intrinsic) and mean (extrinsic) curvatures, which implies that both internal strains and a location of the surface in R 3 may vary. Besides, originally distributed disclinations are taken into account. For the flat surface, an extended variant of the Edelen-Kadi´c gauge ...

The non-relativistic 'Dirac' equation of Lévy-Leblond is used to describe a spin 1/2 particle interacting with a Chern-Simons gauge field. Static, purely magnetic, self-dual spinor vortices are constructed. The solution can be 'exported' to a uniform magnetic background field.

Point transformations for the ordinary differential equations of the form y ′′ = P (x, y) + 3 Q(x, y) y ′ + 3 R(x, y) (y ′) 2 + S(x, y) (y ′) 3 are considered. Some classical results are resumed. Solution for the equivalence problem for the equations of general position is described.

We construct lattice Hamiltonians with homogeneous interaction potentials which allow for explicit breather solutions. Especially we obtain exponentially localized solutions for d-dimensional lattices with d = 2, 3.
