Nonexistence of Almost Complex Structures on the product $S^{2 m} \times M$

Prateep Chakraborty, Ajay Singh Thakur

In this note we give a necessary condition for having an almost complex structure on the product $S^{2 m} \times M$ , where $M$ is a connected orientable closed manifold. We show tha…

Rational homotopy of maps between certain complex Grassmann manifolds

Prateep Chakraborty, Shreedevi K. Masuti

Let $G_{n, k}$ denote the complex Grassmann manifold of $k$ -dimensional vector subspaces of $C^{n}$ . Assume $l, k \leq ⌊ n /2 ⌋$ . We show that, for sufficiently large…
