In this paper the Friedrichs model with rank three perturbation, acting in the Hilbert space is considered. This model is a linear, bounded, and self-adjoint and it is a model operator corresponding to the Hamiltonian of the two particle system on the one-dimensional lattice. The numerical range of the considered Friedrichs model is studied by the numerical ranges of the three auxiliary Friedrichs models with rank one perturbation.

The synthesis of novel thieno[3,2-d]pyrimidine derivatives commenced with 5-bromo-2-chlorobenzonitrile with ethyl-2-mercaptoacetate, which yielded the compound AT-2. The addition of piperidin-2-one to the formed AT-2…
This study investigates the physicochemical properties of nanocomposites based on CdSe/CdS/ZnS triplet quantum dots. Methods for their synthesis, including stepwise deposition of CdS and ZnS shells to improve optical…
We conducted a comprehensive investigation into the relationship between Forbush decreases (FDs), Geomagnetic storms (GS), and Coronal mass ejections (CMEs) during Solar cycles (SC) 23 and 24. GS characterized by the…
Here, we demonstrate that the assembly of nanostructures with different dimensionalities yields “multicomponent hybrid” transparent conductive films (TCFs) with sheet resistance and optical transmittance comparable to…
This paper presents the results of experiments on the technology of obtaining and studying the mechanisms of current transport in a p+––p+ (p+–p–p+) structure based on zinc compensated silicon in the dark and at…
To synthesize new derivatives of quinazolinones by the Buchwald-Hartwig method, 6-bromo-quinazolin-4-one derivatives were initially synthesized using cyclization methods and converted into 6-bromoquinazolin-4-thiones…
This study explores the integral formulations and harmonic fundamental solutions for various media, including elastodynamic, scalar, and poroelastic media. Integral formulations are expressed in terms of boundary…
In this article, a system of logical equations is created using logical functions through methods of expressing the relationship between symptoms of diseases and the diseases themselves in the language of logical…
In this work, the influence of the ratio of stabilisers oleylamine and oleic acid on the optical and structural properties of perovskite KPbBr₃ has been studied. The luminescence, infrared spectroscopy and light…
In this paper we consider the Cauchy problem for the n-order polyharmonic equation in an unbounded domain D, where boundary data are given on a part of boundary. The goal is to reconstruct a polyharmonic function u(y)…
