RT Journal Article T1 Orbital Reversibility of Planar Vector Fields A1 Algaba Durán, Antonio A1 García García, Cristóbal A1 Giné, Jaume AB In this work we use the normal form theory to establish an algorithm to determine ifa planar vector field is orbitally reversible. In previous works only algorithms to determine thereversibility and conjugate reversibility have been given. The procedure is useful in the centerproblem because any nondegenerate and nilpotent center is orbitally reversible. Moreover, using thisalgorithm is possible to find degenerate centers which are orbitally reversible.
