Triple Fixed-sign Solutions in Modelling a System with Hermite Boundary Conditions
We consider the following system of differential equations u i (t) = Pi(t,u1(t),u2(t), . . . , un(t)), t ∈ [0,1], 1 ≤ i ≤ n together with Hermite boundary conditions u j) i (tk) = 0, j = 0, . . . ,mk − 1, k = 1, . . . ,r, 1 ≤ i≤ n, where 0 = t1 < t2 < ··· < tr = 1, mk ≥ 1 for k = 1, . . . ,r, and ∑r k=1mk =m. By using different fixed point theorems, we offer criteria for the existence of three ...
متن کاملExistence and multiplicity of nontrivial solutions for $p$-Laplacian system with nonlinearities of concave-convex type and sign-changing weight functions
This paper is concerned with the existence of multiple positive solutions for a quasilinear elliptic system involving concave-convex nonlinearities and sign-changing weight functions. With the help of the Nehari manifold and Palais-Smale condition, we prove that the system has at least two nontrivial positive solutions, when the pair of parameters $(lambda,mu)$ belongs to a c...
متن کاملExistence of positive solutions for fourth-order boundary value problems with three- point boundary conditions
In this work, by employing the Krasnosel'skii fixed point theorem, we study the existence of positive solutions of a three-point boundary value problem for the following fourth-order differential equation begin{eqnarray*} left { begin{array}{ll} u^{(4)}(t) -f(t,u(t),u^{prime prime }(t))=0 hspace{1cm} 0 leq t leq 1, & u(0) = u(1)=0, hspace{1cm} alpha u^{prime prime }(0) - beta u^{prime prime pri...
متن کاملMultiplicity of Positive Solutions of laplacian systems with sign-changing weight functions
In this paper, we study the multiplicity of positive solutions for the Laplacian systems with sign-changing weight functions. Using the decomposition of the Nehari manifold, we prove that an elliptic system has at least two positive solutions.
متن کاملModel validation for IQC uncertain systems with fixed initial conditions
The paper considers a model validation problem for a class of uncertain systems in which the uncertainty is described by an integral quadratic constraint and the uncertain system has zero initial condition. This leads to a method for model validation which is based around a robust Kalman filter type structure.
