We show that Lagrangian and Legendre varieties associated with matrix singularities and singularities of composite functions are stable in the sense of a natural modification of Givental's notion of stability of Lagrangian projections.
Keywords: Lagrangian variety, stability, matrix singularities, ramified covering
Mots-clés : discriminant.
