APPROXIMATION OF m-CONVEX FUNCTIONS INFINITELY SMOOTH FUNCTIONS
In this paper, we investigate the approximation of 𝑚-convex functions using the relationship between 𝑚-convex functions and 𝑚-subharmonic functions in the complex space ℂ. The main result is a theorem establishing that any 𝑢(𝑥) 𝑚-convex function defined on a domain 𝐷 ⊂ℝ௡ can be approximated by a...

INVESTIGATION OF SCATTERING Ar+ IONS FROM CdSe(001) SURFACE AT THE GLANCING INCIDENCE
In this paper, we present and discuss the energy distributions and characteristic trajectories of scattered Ar+ ions from the CdSe(001) surface at the angles of incidence ψ =3°, 5°, 7° and at the initial energy E0=3 and 5 keV. In the obtained energy spectra, two intense peaks are observed, which...
