Estimates for solutions of Burgers type equations and some applications
We obtain precise large time asymptotics for the Cauchy problem for Burgers
type equations satisfying shock profile condition. The proofs are based on the
exact a priori estimates for (local) solutions of these equations and a recent
result of the first and second authors.Comment: to appear in J. Math. Pure et App
Technological changes on the macroeconomic level—mathematical modeling
We consider two of the technological changes on the macroeconomic level. The first type is due to changes of addresses of mutual deliveries between producers and the second type is due to technological progress
Variational inequalities for economic equilibrium in the model with the deficit of the working capital
New conditions for the existence of equilibrium prices
We study the existence of equilibrium price vector in a supply-demand model taking into account the transaction costs associated with the sale of products. In this model, the demand function is the solution to the problem of maximizing the utility function under budget constraints. The supply function is the solution to the problem of maximizing the profit (with given transaction losses) on the technology set. We establish sufficient conditions for the existence of the equilibrium price vector, which are consequences of some theorems in the theory of covering mappings
