 positive characteristic\n\nAbstract: Localization theorem identifies the ca
 tegory of modules over a semi-simple Lie algebra with D-modules\, which can
  be thought of as a quantization of the cotangent bundle. A surprising obse
 rvation is that in some cases of interest such category O and the category 
 of (g\,K) modules for quasi-split groups (conjecturally in general) the de-
 quantization contains the original category as a full subcategory. I will d
 escribe a strategy for proof via positive characteristic by a version of De
 ligne-Illusie method\, lifting the D-modules to what one can call a Fontain
 e-Laffaille module. Based on a joint work in progress with A. Ionov and D. 
 Davis.
