Triple solutions for a damped impulsive differential equation
In this paper, we aim to obtain the existence of at least three classical solutions for nonlinear impulsive problems neither adding superlinear or local sublinear conditions to nonlinear term at zero nor adding superlinear assumptions to nonlinear term ...

Weak Solutions for a Class of Nonlocal Singular Problems Over the Nehari Manifold
ABSTRACT In this paper, we consider a nonlocal model of dilatant non‐Newtonian fluid with a Dirichlet boundary condition. By using the Nehari manifold and fibering map methods, we obtain the existence of at least two weak solutions, with sign information.

On periodic solutions of superlinear parabolic problems [PDF]
In this paper we study the existence of positive nontrivial periodic solutions of semilinear parabolic problems. Most of the nonlinearities considered are of the superlinear type. Some bifurcation results are proved as well.

Upper and lower solutions for a second-order three-point singular boundary-value problem
We study the singular boundary-value problem $$displaylines{ u''+ q(t)g(t,u)=0,quad t in (0,1),; eta in (0,1),;gamma >0cr u(0)=0, quad u(1)=gamma u(eta),.

Interplanetary Electric Fields for Extreme Magnetic Storms
Abstract Using a list of sudden‐commencement storms, the ring‐current index, and 1‐h near‐Earth solar‐wind measurements from solar cycles 20–25, we develop extreme‐value statistical models relating storm intensity D=max{−Dst} $D=\max \left\{-Dst\right\}$ to the storm main‐phase maximum duskward interplanetary electric field E $E$.

Infinitely Many Nontrivial Solutions of Resonant Cooperative Elliptic Systems with Superlinear Terms
We study a class of resonant cooperative elliptic systems and replace the Ambrosetti-Rabinowitz superlinear condition with general superlinear conditions.

A 3D‐Printed Blister Test Platform for Quantifying Biointerface Adhesion Mechanisms
A 3D‐printed blister platform enables energy‐resolved characterization of soft hydrogel–rigid interfaces. Integrating precision pressure control with hyperelastic modeling directly quantifies adhesion energy (G) and R‐curve toughening. Results reveal that modulating hydrogel concentration and surface roughness drives a tunable transition from cohesive ...

Three nontrivial solutions for the p-Laplacian Neumann problems with a concave nonlinearity near the origin [PDF]
We consider a nonlinear Neumann problem driven by the p- Laplacian, with a right-hand side nonlinearity which is concave near the origin. Using variational techniques, combined with the method of upper-lower solutions and with Morse theory, we show ...

Elliptic problems with superlinear convection terms [PDF]
In this manuscript we deal with elliptic equations with superlinear first order terms in divergence form of the following type −div(M(x)∇u)=−div(h(u)E(x))+f(x), where M is a bounded elliptic matrix, the vector field E and the function f belong to ...
