Algebraic Systems with Positive Coefficients and Positive Solutions
Algebraic Systems with Positive Coefficients and Positive Solutions
The paper is devoted to the existence, uniqueness and nonuniqueness of positive solutions to nonlinear algebraic systems of equations with positive coefficients. Such systems appear in large numbers of applications, such as steady-state equations in continuous and discrete dynamical models, Dirichlet problems, difference equations, boundary value problems, periodic solutions and …
