Titel: |
Number systems and fractals |
| Speaker: |
Lucía Rossi (TU Wien) |
| Inhalt: |
We study cluster structures on spinor helicity and momentum twistor varieties which describe the kinematic spaces of
massless scattering. Both varieties are certain partial flag varieties. We exhibit embeddings of the corresponding cluster
algebras into cluster algebras of sufficiently large Grassmannians and show how the former is obtained by freezing certain cluster
variables from the latter. This is joint work with Lara Bossinger. |
