DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NASO/17/">Po
 lynomial functors as affine spaces</a>\nby Arthur Bik (Universität Bern) 
 as part of Max Planck Institute nonlinear algebra seminar online\n\n\nAbst
 ract\nPolynomial functors are like spaces of objects (e.g. k-way tensors) 
 without fixed size and come with an action of (products of) general linear
  groups. The aim of this talk is to answer the following question: what ha
 ppens when you replace vector spaces by polynomial functors when defining 
 affine spaces?\n\nI will define polynomial functors\, the maps between the
 m and their Zariski-closed subsets and give examples of these things. Then
 \, I will discuss how to extend some of the basic results from affine alge
 braic geometry to this setting. This is joint work with Jan Draisma\, Rob 
 Eggermont and Andrew Snowden.\n
