On the fundamental groups of perforated surfaces

Khushbu Gulati, Parameswaran Sankaran

A perforated surface is the complement $Σ ˚ := Σ ∖ A$ of a countable dense subset $A$ in a connected paracompact surface $Σ$ . It is known that the topological type of $…

THE K-RING OF E_6/Spin(10)

Sudeep Podder, Parameswaran Sankaran

Let $E_{6}$ denote the simply-connected compact exceptional Lie group of rank 6. The Lie group $S p in (10)$ naturally embeds in $E_{6}$ , corresponding to the incl…

K-theory of real Grassmann manifolds

Sudeep Podder, Parameswaran Sankaran

Let $G_{n, k}$ denote the real Grassmann manifold of $k$ -dimensional vector subspaces of $R^{n}$ . Using the Hodgkin spectral sequence, we compute the complex $K$ -ring of $G_{n…

K-theory of Springer varieties

Parameswaran Sankaran, Vikraman Uma

The aim of this paper is to describe the topological $K$ -ring, in terms of generators and relations, of a Springer variety $F_{λ}$ of type $A$ associated to a nilpotent ope…

Cohomology of generalized Dold spaces

Manas Mandal, Parameswaran Sankaran

Let $(X, J)$ be an almost complex manifold with a (smooth) involution $σ : X \to X$ such that fix( $σ$ ) is non-empty. Assume that $σ$ is a complex conjugation, i.e, the differential of…

Picard groups of certain compact complex parallelizable manifolds and related spaces

Pritthijit Biswas, Parameswaran Sankaran

Let $G$ be a complex simply connected semisimple Lie group and let $Γ$ be a torsionless uniform irreducible lattice in $G$ . Then $Γ\ G$ is a compact complex non-Kähler man…
