Maps between certain complex Grassmann manifolds

Prateep Chakraborty, Parameswaran Sankaran

Let $k, l, m, n$ be positive integers such that $m - l \geq l > k, m - l > n - k \geq k$ and $m - l > 2 k^{2} - k - 1$ . Let $G_{k} (C^{n})$ denote the Grassmann manifold of $k$ -dimensional vector subspa…

Formality of certain CW complexes

Prateep Chakraborty, Parameswaran Sankaran

Let $X$ be a simply connected path connected topological space which is formal in the sense of rational homotopy theory. Let $Y = X \cup_{α} D^{n}$ where $α:\mathbb{S}^{n-1}\to…
