Stable parallelizability of partially oriented flag manifolds
Stable parallelizability of partially oriented flag manifolds
This paper solves the questions of stable parallelizability and parallelizability for the family of partially oriented (p.o.) flag manifolds, except for a few undecided cases.In particular, for the oriented Grassmannians G k (R n ) it is proved that apart from the spheres S 1 , S 3 , and …
