Cohomology in algebra, geometry, physicsand statistics

Complex reflection groups and classification of $3$-forms in $R^9$ and of $4$-forms in $R^8$

In my talk   I shall    discuss  the role  of complex reflection  groups in  Vinberg-Elashvili's  classification of 3-forms  in $C^9$, Antonyan's classification  of  4-forms  in $C^8$ and Borovoi-De  Graaf-Lê's  classification of 3-forms  in  $R^9$. I shall  also  explain   the role  of complex reflection  groups  in   classification  of   4-forms  in $R^8$.
