- Аннотация: It is discussed in detail the complete mathematical model of gravitational lensingon a single cosmic string (CS) of general shape and position with respect tothe line of sight. CS are one-dimensional extended objects assuredly predictedby modern cosmology. The presence of CS changes the global geometry of theUniverse, could clarify the properties of the early Universe, including inflationmodels, and could serve as a unique proof of higher-dimensional theories. Despitethe fact that CS have not yet been reliable detected, there are several strong independentindications of the existence of the CS, based of CMB analysis and searchof gravitational lens chains with special properties (The recent new indication ofthe existence of the CSs is the nHz gravitational waves in the NANOGrav andother PTA Collaborations data.) However, early considered models of straight CSpresented only a small fraction of the general CS-configurations to be observed.Now we propose model which could significantly increase the possibilities ofCS observational search. It is considered more realistic models have necessarilyinclude the inclinations and bends of the CS. Besides, the recent analysis ofobservational data on the search for gravitational-lens candidates, shows a largenumber of pairs that could be explained by the complex geometry of the CS.Accept (01-Sep-2023)
