【 摘 要 】

This paper is devoted to the investigation of conformally-related variants of the modified tensor-scalar Jordan theory on the example of determination of the comparative characteristics of the model Universe in «Einstein» and «proper» frames. Within the framework of this model, we consider the possibility for the accelerated expansion of the Universe at the recent epoch.
