| Abstract | We are interested in the existence and asymptotic behavior of sign-changing solutions to the following nonlinear Schrödinger–Poisson system $$\left\{\begin{array}{ll}-\Delta u+V(x)u+\lambda \phi(x)u =f(u), \ &\quad x \in \mathbb{R}^3,\\ -\Delta \phi=u^2, \ &\quad x \in \mathbb{R}^3,\end{array}\right.$$ where V(x) is a smooth function and λ is a positive parameter. Because the so-called nonlocal term $${\lambda \phi_u(x)u}$$ is involving in the equation, the variational functional of the equation has totally different properties from the case of $${\lambda=0}$$ . Under suitable conditions, combining constraint variational method and quantitative deformation lemma, we prove that the problem possesses one sign-changing solution $${u_\lambda}$$ . Moreover, we show that any sign-changing solution of the problem has an energy exceeding twice the least energy, and for any sequence $${\{\lambda_n\} \rightarrow 0^+(n \rightarrow \infty)}$$ , there is a subsequence $$\{\lambda_{n_k}\}$$ , such that $${u_{\lambda_{n_k}}}$$ converges in $${H^1(\mathbb{R}^3)}$$ to $${u_0}$$ as $${k\rightarrow \infty}$$ , where $${u_0}$$ is a sign-changing solution of the following equation $$-\Delta u+V(x)u=f(u),\quad \ x \in \mathbb{R}^3$$ . |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
