The existence of contact structures on 9-manifolds
Diarmuid Crowley, Huijun Yang
We give necessary and sufficient conditions for a closed orientable 9-manifold M to admit an almost contact structure. The conditions are stated in terms of the Stiefel-Whitney cla…
Topological classification of complex vector bundles over -dimensional spin manifolds
Huijun Yang
In this paper, complex vector bundles of rank over -dimensional spin manifolds are classified in terms of the Chern classes of the complex vector bundles and the cohom…
Connected sums of almost complex manifolds
Huijun Yang
In this paper, firstly, for some -dimensional almost complex manifolds , we prove that $\left(\sharp_{i=1}^α M_{i}\right) \sharp (α{-}1) \mathbb{C} P^{2n}…
Stable almost complex structures on certain -manifolds
Huijun Yang
Let be a -dimensional closed oriented smooth manifold. Set Suppose tha…
Some remarks on stable almost complex structures on manifolds
Huijun Yang
Let be an -dimensional pathwise connected -complex with or and , be a real vector bundle over . Suppose that admits a stable complex str…
Almost Complex Structures on (n-1)-connected 2n-manifolds
Huijun Yang
Let M be a closed (n-1)-connected 2n-dimensional smooth manifold with n > 2. In terms of the system of invariants for such manifolds introduced by Wall, we obtain necessary and suf…
