Fwd: Algebra and geometry seminar 04/06

[Francesco Galuppi]

Dear colleagues,

this is to advertise the weekly seminar of the Algebra and geometry 
group of University of Trieste. On Friday, June 4th at 10:30, Yairon 
Cid-Ruiz (Ghent University) will talk about "Primary decomposition with 
differential operators".

We introduce 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 differential primary decompositions are unique up 
to change of bases. Our results 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 addressed. This is joint 
work with Bernd Sturmfels.

The seminar will take place online. The Zoom link is

You are welcome to extend the invitation to anyone interested.

All the best,
Francesco
