dc.description.abstractIn this work, we present a formula to compute the Euler obstruction of a function f: (X, 0) → (C, 0) and its Brasselet number, where X is a multitoric surface. As an application of this formula, we compute the Euler obstruction of a function on some families of determinantal surfaces.en
