    • Filtered Dehomogenization Theory For The Micro-structure sheves OY 

      Radwan, Abd El-Aziz E. [عبد العزيز رضوان] ( Qatar University , 1999 , Article)
      In this work we study the theory of dehomogenization at the level of filtered sheaves using the micro-structure sheaves. For the sheaf of quantum section the results are still true.

    • Morphisms Of Affine Schemes And Equivalence Of Categories 

      Radwan, Abd El-Aziz E. [عبد العزيز رضوان] ( Qatar University , 1996 , Article)
      In this work we construct the relation between the category R-filt (G(R)-gr) and the category O^ — Filt(O^ — Gr). The quantum (ungraded) version of this result can be obtained by restricting to parts of zero degree. ...
