    • Corrigendum to “Oscillatory motions in restricted N-body problems” [J. Differential Equations 265 (2018) 779–803] 

      Álvarez-Ramírez, Martha; Rodríguez García, Antonio Upna Orcid; Palacián Subiela, Jesús Francisco Upna Orcid; Yanguas Sayas, Patricia Upna Orcid (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      At the beginning of paper [1] there is an error that spreads along the rest of the work and the conclusions are not correct in their present form. Precisely, in Section 2, page 783, there is a contradiction related to the ...
