Taking into account the conditions of the real functioning of companies, one of the most striking effects in financial management is investigated: the “golden age” of the company (when the cost of capital raised is below the perpetuity limit, and

The famous Capital Asset Pricing Model (CAPM), widely used in practice, takes into account only the business risk associated with investments in a specific company [not the entire market (or industry)]. In practice, most listing companies use debt fi

The recent rise in inflation in Europe, caused by the pandemic, the increase in prices for energy resources and the violation of the logistics of energy supplies, has led to a decrease in company income. This makes it relevant to study the financial

The paper is devoted to application of Brusov-Filatova-Orekhova theory (BFO theory) and Modigliani-Miller theory (MM theory) in rating. A serious modification of both theories in order to use them in rating procedure has been required. The financial

We investigate the problem of the existence of the Green–Samoilenko function for linear expansions of dynamical systems on a torus of the form $$\frac{{d\phi }}{{dt}} = a(\phi ),{\text{ }}C(\phi )\frac{{d\phi }}{{dt}} + \frac{1}{2}\dot C(\phi )x =

By using Lyapunov functions with alternating signs, we study problems of regularity and weak regularity for some linear extensions of dynamical systems on a torus.

The problem of the existence of quadratic forms that have a positive definite derivative along the solutions of linear extensions of dynamical systems on a torus is considered. Assuming the existence of quadratic forms whose derivative is positive de

We found new structures of linear extensions of dynamical systems on a torus which have a unique Green's function.
