In this talk, we address the advances in the study of Gutierrez-Sotomayor singular flow (GS flow, for short) on closed singular 2-manifolds. We make use of the Conley Index Theory to describe the change in the topology of the level set of a singular surface as one passes through a GS singularity (cone, cross-cap, double crossing and triple crossing singularities). Moreover, we explore the dynamical behaviour of GS-singularities within GS-flows through homotopical perturbations to achieve a « minimal flow » into the class of homotopy equivalent spaces. This is done by describing the qualitative aspects of the flow in terms of a chain complex generated by the singularities of the flow and establishing a homotopical cancellation theory of GS-singularities.
