We prove that the local dynamics around the fixed points related to the roots of $p$ depend on the parity of $d$.12 p.application/pdfeng(c) American Institute of Mathematical Sciences (AIMS), 2020Teoria de la bifurcacióSistemes dinàmics diferenciablesBifurcation theoryDifferentiable dynamical systemsinfo:eu-repo/semantics/article6959942023-07-05info:eu-repo/semantics/openAccess
