Formal microlocalization. (English. Abridged French version) Zbl 0945.58019
Let $$X$$ be a complex analytic manifold. A functor of formal cohomology on $$X$$ has previously been considered by M. Kashiwara and P. Schapira [Mém. Soc. Math. Fr., Nouv. Sér. 64, 76 p.(1996; Zbl 0881.58060), Suppl. Bull. Soc. Math. Fr. 124, No. 1 (1996)].
In this note, a microlocal version of this functor is presented, an associated Sato triangle is given, and the existence of a natural action of the ring $${\mathcal E}^{R,f}_X$$ is concluded.
