TY - JOUR AU - Wang, Yaqi AU - Zhao, Zengqin PY - 2017 DA - 2017/02/08 TI - Existence and multiplicity of solutions for a second-order impulsive differential equation via variational methods JO - Advances in Difference Equations SP - 46 VL - 2017 IS - 1 AB - In this paper, we study the existence and multiplicity of solutions for an impulsive differential equation via some critical point theory and the variational method. We extend and improve some recent results and reduce conditions. SN - 1687-1847 UR - https://doi.org/10.1186/s13662-017-1075-8 DO - 10.1186/s13662-017-1075-8 ID - Wang2017 ER -
