00925njm 22002777a 4500 dc Álvarez Torres, María Jesús author Ferragut Amengual, Antoni Manel author Jarque i Ribera, Xavier author 2011 The blow up technique is widely used in desingularization of degenerate singular points of planar vector fields. In this survey we give an overview of the different types of blow up and we illustrate them with many examples for better understanding. Moreover, we introduce a new generalization of the classical blow up. Planar differential system Degenerate singular point Blow up A survey on the blow up technique
