Equivariant Giambelli and determinantal restriction formulas for the Grassmannian
V. Lakshmibai, K. N. Raghavan, P. Sankaran
The main result of the paper is a determinantal formula for the restriction to a torus fixed point of the equivariant class of a Schubert subvariety in the torus equivariant integr…
Orbits of certain endomorphisms of nilmanifolds and Hausdorff dimension
C. S. Aravida, Parameswaran Sankaran
We prove that for certain endomorphisms of a nilmanifold N the set S of those points such that the closure of its (forward) orbit contains no periodic points is large in the sense…
Bounded automorphisms and quasi-isometries of finitely generated groups
Aniruddha C. Naolekar, Parameswaran Sankaran
Let G be any finitely generated infinite group. Denote by K(G) the FC-centre of G, i.e., the subgroup of all elements of G whose centralizers are of finite index in G. Let QI(G) de…
Cohomology of toric bundles
P. Sankaran, V. Uma
We describe the singular cohomology ring, the K-ring of complex vector bundles, the Chow ring, and the Grothendieck ring of coherent sheaves of the total space of the fibre bundle…
A coincidence theorem for holomorphic maps to G/P
Parameswaran Sankaran
We show that any two holomorhpic maps, not both of which are constant, from a generalized Hopf manifold to its base must have a coincidence. We prove a similar result for holomorph…
