Once the existence of an inverse integrating factor is established, we study the systems having a center. Among others, we characterize the centers of the perturbations of the system $-y^3\partial_x+x^3\partial_y$ having an algebraic inverse integrating factor.}, organization = {This work has been partially supported by Ministerio de Ciencia y Tecnología, Plan Nacional I+D+I co-financed with FEDER funds, in the frame of the project MTM2014-56272-C2, and by Consejería de Educación y Ciencia de la Junta de Andalucía (FQM-276 and P12-FQM-1658).}, publisher = {American Institue of Mathematical Sciences}, title = {Non-formally integrable centers admitting an algebraic inverse integrating factor}, author = {Algaba Durán, Antonio and Fuentes Díaz, Natalia and García García, Cristóbal and Reyes Columé, Manuel}, }
