The Vector Field Problem for Homogeneous Spaces,ry .. The number . is called the span of ., written .. It is clear that .. The vector field problem is an important and classical problem in differential topology. In this survey, we shall consider the vector field problem focussing mainly on the class of compact homogeneous spaces.

Moreover, we show that these .-local homotopy groups can be expressed as a direct sum of .-local homotopy groups of spheres. The integral homotopy type of the loop space i

Methods from .-cohomology are brought to bear on the question and relate it to other open problems on low-dimensional complexes—some introduced here—as well as open problems on group theory, such as the Kervaire–Laudenbach Conjecture, and on group algebras, like the Bass trace conjecture.
