Using the differential geometry of curves and surfaces the Lakshmanan equivalent counterpart of the M-XXII equation is found. It is shown that these equations are too gauge eqivalent to each other. Also the gauge equivalence ...

In this paper we consider the problem of radiation from a vertical short (Hertzian) dipole above flat ground with losses, which represents the well – known in the literature ‘Sommerfeld radiation problem’. We end up with ...

The study of the relation between the Weierstrass inducing formulae for constant mean curvature surfaces and the completely integrable euclidean nonlinear σ-model suggests a connection among integrable σ-models in a ...

The Einstein equation for the Friedmann-Robertson-Walker metric plays a fundamental role in cosmology. The direct search of the exact solutions of the Einstein equation even in this simple metric case is sometime a hard ...

In this paper we study the structure and thermochemical properties of some new polycarbonyl compounds, with particular attention devoted to the study of (CO)n complexes, which are expected to be present in magnegasesTM. ...

In this letter we obtain an exact solution for cylindrically symmetric modified Gauss Bonnet grav- ity. This metric is a generalization of the vacuum solution of the Levi-Civita in the general relativity. It describes ...

We present the results of calculations of surface relaxations, rumplings, and charge distribution for the MgF 2 (0 0 1) and (0 1 1) surfaces using ab initio code Crystal-2003 and the hybrid exchange-correlation B3PW ...

The results of ab initio slab calculations of surface relaxations, rumplings and charge distribution for the different terminations of the MgF2 (011) and (111) polar surfaces are presented and discussed. We have employed ...
