From the introduction: “There is an important literature dealing with integral transformations. In our papers [A. D’Agnolo and P. Schapira, J. Funct. Anal. 139, No. 2, 349-382, Art. No. 0089 (1996); Duke Math. J. 84, No. 2, 453-496 (1996) and C. R. Acad. Sci., Paris, Sér. I 319, No. 5, 461-466 (1994; Zbl 0827.32008)], we proposed a general framework to the study of such transformations in the language of sheaves and \(D\)-modules. In particular, we showed that there are two natural adjunction formulas.”
“Here, we shall first recall the four above mentioned adjunction formulas, and then concentrate our study on the \(D\)-module theoretical transform. Given two complex manifolds \(X\) and \(Y\) and a \(D\)-module kernel which defines a quantized contact transformation on an open subset of \(T^{\ast} (X \times Y)\), our main result gives a geometrical condition to extend it as an isomorphism of locally free \(D\)-modules of rank one. This improves our previous result of the third paper, cited above”.
