In this paper we survey methods and results of classification of 𝑘-forms (resp. 𝑘-vectors on R𝑛), understood as description of the orbit space of the standard GL(𝑛,R)-action on Λ𝑘R𝑛* (resp. on Λ𝑘R𝑛). We discuss the existence of related geometry defined by differential forms on smooth manifolds. This paper also contains an Appendix by Mikhail Borovoi on Galois cohomology methods for finding real forms of complex orbits.
