Exact Solutions of the Two-Dimensional Cattaneo Model Using Lie Symmetry Transformations
Discrete Dynamics in Nature and Society, 2021 In this article, symmetry technique is utilized to obtain new exact solutions of the Cattaneo equation. The infinitesimal symmetries, linear combinations of these symmetries, and corresponding similarity variables are determined, which lead to many exact

Effective Capital in Upgraded Solow Macro-Model of Economic Growth
Вестник Российского экономического университета имени Г. В. Плеханова, 2022 The article studies the macro-economic theory of economic growth Solow in complicated case, when technical progress is materialized in capital. In this situation the production function depends on effective capital and labour resource.

On the discrete and continuous Miura Chain associated with the Sixth Painlevé Equation [PDF]
, 1999 A Miura chain is a (closed) sequence of differential (or difference) equations that are related by Miura or B\"acklund transformations. We describe such a chain for the sixth Painlev\'e equation (\pvi), containing, apart from \pvi itself, a Schwarzian ...
