On the existence of infinitely many solutions to a damped sublinear boundary-value problem

Electronic Journal of Differential Equations, 2001
We prove the existence of infinitely many solutions (with prescribed nodal properties) to a damped sublinear boundary-value problem. The proofs are performed by means of an abstract continuation theorem and the time-map technique for strongly nonlinear ...

Homogeneous Grand Mixed Herz–Morrey Spaces and Their Applications

Axioms
In this paper, we introduce the homogeneous grand mixed Herz–Morrey spaces MK˙q˜,λα,p),θ(Rn) and investigate their fundamental properties. We further explore the boundedness of sublinear operators and fractional-type operators on these spaces ...

Positive solutions of fourth-order problems with dependence on all derivatives in nonlinearity under Stieltjes integral boundary conditions

Boundary Value Problems, 2019
In this article, we investigate the existence of positive solutions to fourth-order problems with dependence on all derivatives in nonlinearities subject to the Stieltjes integral boundary conditions {u(4)(t)=f(t,u(t),u′(t),u″(t),u‴(t)),t∈[0,1],u′(0)+β1 ...

Boundedness of sublinear operators on two-weighted grand Herz spaces with variable exponent

Journal of Inequalities and Applications
In this article, we introduce the concept of two-weighted grand variable Herz spaces as a natural generalization of variable Herz spaces. We establish the boundedness of sublinear operators within this framework, offering significant insights into their ...

Boundedness of fractional sublinear operators on weighted grand Herz-Morrey spaces with variable exponents

Open Mathematics
This article aims to delve deeper into the weighted grand variable Herz-Morrey spaces, and try to establish the boundedness of fractional sublinear operators and their multilinear commutators within this framework.

Weighted estimates for a class of sublinear operators

Doklady Mathematics, 2013
Let \(M\) be the class of Lebesgue measurable functions defined on \((0,\infty)\), and let \(M^\ast :=\{f\in M:f\geq 0\}\). The paper under review is concerned with some sublinear operators with nonnegative measurable kernel functions defined on the cone \(M^\ast\).

Positive solutions for higher order ordinary differential equations

Electronic Journal of Differential Equations, 1995
obtained for the boundary value problem, $u^{(n)} + a(t)f(u) = 0$, $u^{(i)}(0) = u^{(n-2)}(1)= 0$, $0 leq i leq n-2$, in the cases that $f$ is either superlinear or sublinear.

Nonhomogeneous quasilinear elliptic systems with small perturbations and lack of compactness

Bulletin of Mathematical Sciences
We investigate a class of quasilinear elliptic system involving a nonhomogeneous differential operator which is introduced by Stuart [Milan J. Math. 79 (2011) 327–341] and depends not only on [Formula: see text] but also on u.
