Multiplicity results for sign-changing solutions of an operator equation in ordered Banach space [PDF]
, 1972 summary:In this paper, we prove some multiplicity results for sign-changing solutions of an operator equation in an ordered Banach space. The methods to show the main results of the paper are to associate a fixed point index with a strict upper or lower ...

High energy sign-changing solutions for Coron's problem [PDF]
, 2021 We study the existence of sign changing solutions to the following problem {Δu+|u|p−1u=0inΩε;u=0on∂Ωε, where [Formula presented] is the critical Sobolev exponent and Ωε is a bounded smooth domain in Rn, n≥3, of the form Ωε=Ω\B(0,ε).

On finding sign-changing solutions [PDF]
, 2006 Some parameter-depending linking theorems are established, which allow to produce a bounded and sign-changing Palais–Smale sequence. For even functionals, a parameter-depending fountain theorem is obtained which provides infinitely many bounded and sign ...

Multiplicity of sign-changing solutions for Kirchhoff-type equations [PDF]
, 2019 We are concerned with sign-changing solutions to nonlocal perturbation of the nonlinear Schrödinger equation in the whole R 3 . By using the method of invariant sets of descending flow, we prove the existence of multiple sign-changing solutions provided

Multiple and least energy sign-changing solutions for Schrodinger-Poisson equations in R3 with restraint [PDF]
, 2017 In this paper, we study the existence of multiple sign-changing solutions with a prescribed Lp+1−norm and theexistence of least energy sign-changing restrained solutions for the following nonlinear Schr¨odinger-Poisson system:By choosing a proper ...

Nontrivial Solutions for Periodic Schrödinger Equations with Sign-Changing Nonlinearities [PDF]
, 2015 We prove a new infinite-dimensional linking theorem. Using this theorem, we obtain nontrivial solutions for strongly indefinite periodic Schrödinger equations with sign-changing ...

On sign-changing solutions for nonlinear operator equations [PDF]
, 2006 In this paper, the existence of sign-changing solutions for nonlinear operator equations is discussed by using the topological degree and fixed point index theory. The main theorems are some new three-solution theorems which are different from the famous

Solutions for m-Point BVP with Sign Changing Nonlinearity
Discrete Dynamics in Nature and Society, 2009 We study the existence of positive solutions for the following nonlinear m-point boundary value problem for an increasing homeomorphism and homomorphism with sign changing nonlinearity: {(ϕ(u′(t)))′+a(t)f(t,u(t))=0 ...

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids
Pediatric Blood &Cancer, EarlyView.ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...
