The present paper focus on Lagrangian distributions with complex phase. We provide an alternative construction of their principal symbol map, which allows us to compute the principal symbol after clean composition of Fourier integral operators with complex phase.

El presente artículo se centra en el estudio de las distribuciones lagrangianas con fase compleja. Proponemos una construcción alternativa del símbolo principal, que nos permite calcular el símbolo principal de la distribución resultante de la composición de operadores integrales de Fourier con fase compleja.
