Diagonal Subschemes and Vector Bundles
Piotr Pragacz, Vasudevan Srinivas, Vishwambhar Pati
We study when a smooth variety , embedded diagonally in its Cartesian square, is the zero scheme of a section of a vector bundle of rank on . We call this t…
Subfactors and 1+1-dimensional TQFTs
Vijay Kodiyalam, Vishwambhar Pati, V. S. Sunder
We construct a certain `cobordism category' whose morphisms are suitably decorated cobordism classes between similarly decorated closed oriented 1-manifolds, and show th…
Unitary Tridiagonalisation in M(4, C)
Vishwambhar Pati
A question of interest in Linear Algebra is whether all n x n complex matrices can be unitarily tridiagonalised. The answer for all n not equal to 4 (affirmative or negative) has b…
The Theorem of Kronheimer-Mrowka
Vishwambhar Pati
This note is an exposition of the proof of Thom's conjecture by Kronheimer and Mrowka, using the new Seiberg-Witten invariants.
Seiberg-Witten Invariants-An Expository Account
Kapil Paranjape, Vishwambhar Pati
In this note, we give an exposition of the construction of Seiberg-Witten invariants.
