DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SFUQNTAG/36/
 ">Primary decomposition with differential operators.</a>\nby Yairon Cid-Ru
 iz (Ghent University) as part of SFU NT-AG seminar\n\n\nAbstract\nWe intro
 duce differential primary decompositions for ideals in a commutative ring.
  Ideal membership is characterized by differential conditions. The minimal
  number of conditions needed is the arithmetic multiplicity. Minimal diffe
 rential primary decompositions are unique up to change of bases. Our resul
 ts generalize the construction of Noetherian operators for primary ideals 
 in the analytic theory of Ehrenpreis-Palamodov\, and they offer a concise 
 method for representing affine schemes. The case of modules is also addres
 sed. This is joint work with Bernd Sturmfels.\n
