An online session of the Algebra and Logic Seminar will be held on March 19, 2021 (Friday) at 4:00 p.m.

A talk on

will be delivered by Andreas Weiermann (Ghent University, Belgium).

Abstract. 

In the first part we will survey the role of transfinite numbers in the study of Hilbert’s basis theorem and its extension by MacLagan. To this end we associate ordinals to some natural well partial orderings related Cartesian products of the set of natural numbers and we apply this apparatus to monomial ideals in F[X_1,…,X_n] where F is a field.

In the second part we use the machinery of Tauberian theorems to prove some structural results about transfinite numbers regarding limit laws and phase transitions.

The talk will be non technical and it is aimed at a general mathematical audience.

 

The seminar will be held via Zoom and everyone can join via the link:
