Abstract :
In this paper we give a formula to calculate the Euler obstruction of a complex analytic singularity in the spirit of the Lefschetz Theorem on hyperplane sections. Namely, we show that the Euler obstruction of a singularity is obtained from the Euler obstructions of the singularities of a general hyperplane section passing near the singularity.
