In this paper we consider a spectral problem for ordinary differential equations of fourth
order with the spectral parameter contained in three of the boundary conditions. We study …

Based on the abstract theory of pullback attractors of non-autonomous non-compact
dynamical systems by differential equations with both dependent-time deterministic and …

In this article, we consider a discrete right-definite Sturm-Liouville problems with two
squared eigenparameter-dependent boundary conditions. By constructing some new …

In this paper, inverse problems are studied for Sturm–Liouville difference operators having p
2− 1/4 m 2 type singularity. First, we define the Green's function and the corresponding Weyl …

This paper is devoted to the study of the spectral properties of one eigenvalue problem for
the fourth-order ordinary differential equations with a spectral parameter contained in two of …

In this paper, we investigate the existence of positive solutions for a class of fractional
boundary value problems involving q-difference. By using the fixed point theorem of cone …

In this paper, we consider the local and global bifurcation of nonnegative nonconstant
solutions of a general Brusselator model {− d 1△ u= a−(b+ 1) f (u)+ u 2 v, x∈ Ω,− d 2△ v= bf …

Consider the linear eigenvalue problem of fourth-order y (4)(x)−(q (x) y (x))= λy (x), 0< x< l, y

In this paper, we mainly consider a kind of discrete second-order boundary value problem
with fully nonlinear term. By using the fixed-point index theory, we obtain some existence …

Let T> 1 be an integer, T≔[1, T] Z={1, 2,…, T}, T ˆ≔{0, 1,…, T+ 1}. In this article, we are
concerned with the global structure of the set of sign-changing solutions of the discrete …
