A related infinitesimal-birational duality realized by a Springer type resolution of singularities and the Fourier transformation is presented. This algebro-geometrical duality is quantized in appropriate sense and its quantum origin is explained.18 pagesAlgebraic GeometryQuantum Algebra16S32 (Primary), 16S30 (Secondary)An infinitesimal-birational duality through differential operatorstext
