Existence of Positive Solution for a Fourth-order Differential System with Variable Coefficients [PDF]
Scientific Bulletin of the ''Petru Maior" University of Tîrgu Mureș, 2015 This paper investigates the existence of positive solutions for a fourth-order differential system using a fixed point theorem of cone expansion and compression type. The two main results give sufficient conditions to insure at least one and at least two

Positive solution for a fractional singular boundary value problem with p-Laplacian operator
, 2018 In this paper, we consider a fractional singular three-point boundary value problem with p-Laplacian operator. The nonlinearity f(t,u)$f(t,u)$ may be singular at t=0,1$t = 0,1$ and u=0$u = 0$. Some properties of the associated Green function are obtained.

Equilibrium solution to the lowest unique positive integer game
, 2010 We address the equilibrium concept of a reverse auction game so that no one can enhance the individual payoff by a unilateral change when all the others follow a certain strategy.

On existence of positive periodic solutions [PDF]
Monatshefte f�r Mathematik, 1998 We present the geometric method for detecting periodic solutions of time periodic nonautonomous differential equations in interior of convex subset of euclidean space. The method is based on the Lefschetz fixed point theorem and the topological principle of Wazewski. Two applications to the existence of positive periodic solutions are considered.
