Degrees of Maps and Cohomological Rigidity of Partial Flag Manifolds
Manas Mandal
We study the existence of continuous maps with nonzero Brouwer degree between partial flag manifolds. We prove that every continuous map between distinct complex or quaternionic pa…

Rigidity of cohomology automorphisms of homogeneous spaces and coincidence theory
Manas Mandal, Divya Setia
We obtain a rigidity phenomena of rational cohomology automorphisms of certain homogeneous spaces, in the presence of external cohomology classes arising from spaces with trivial c…
