On intersection cohomology with torus action of complexity one, II
Marta Agustin Vicente, Narasimha Chary Bonala, Kevin Langlois
We show that the components, appearing in the decomposition theorem for contraction maps of torus actions of complexity one, are intersection cohomology complexes of even codimensi…

On the GIT quotient of Grassmannians by one dimensional torus
Narasimha Chary Bonala, S Senthamarai Kannan, Santosha Pattanayak
We consider the action of the one-parameter subgroup of the special linear group corresponding to a simple root on Grassmannians and describe the structure of the associated Geomet…
