3. RESEARCH AND OTHER SCIENTIFIC ACTIVITIES

MATHEMATICS and STATISTICS

Cryptography:

We continue with our work on Attribute Based Encryptions(ABE)..We proposed efficient fully secure Attribute-Based Encryption Schemes for General Access Structures. We have obtained Ciphertext Policy(CP) and Key Policy(KP) encryption schemes for monotone access structures whose ciphertext size or key size depends only on the number of minimal sets. We have also obtained a CP-ABE scheme with constant size key and

a Hierarchical (H) KP-ABE scheme with constant size ciphertext for arbitrary access structures (not necessarily monotone.

(Rana Barua and Tapas Pandit)

Continuing with our study of signature and signcryption schemes, we have proposed a variant of Ring Signature which we called Ring Signature with designated Identity Verifier. We show that it has all the desired security properties.

(Rana Barua with Sumit Pandey)

Non-Commutative Geometry:

We continue our research on quantum isometry groups. It has been proved that there does not exist any genuine quantum group isometry of a classical compact manifold which is stably parallelizable.

(Debashish Goswami, Soumalya Joardar and Biswarup Das)

Some new results are proved towards the existence of a universal object in the category of compact quantum groups acting isometrically and in a measure-preserving way on certain class of metric measure spaces.

(Debashish Goswami)

Commutative Algebra:

A general structure theorem for locally Laurent polynomial algebras has been established. It has been shown that any faithfully flat algebra over a Noetherian normal domain R, whose generic and codimension-one fibres are Laurent polynomial algebras in n variables over R, is a locally Laurent polynomial algebra in n variables over R. A minimal sufficient condition for a faithfully flat algebra over an arbitrary Noetherian domain to be locally Laurent polynomial has been obtained.

(S. M. Bhatwadekar and Neena Gupta)

The structure and properties of a faithfully flat algebra over a Noetherian normal domain whose generic and codimension one fibres are A** is being investigated.

(Neena Gupta)

An example has been constructed which shows that when R is a two dimensional complete regular local ring with an algebraically closed residue field and A is a Noetherian normal Rsubalgebra of R[X] then A need not be finitely generated over R. Sufficient conditions for A to be finitely generated have been given. Conditions for A to be Noetherian are being investigated.

(Neena Gupta and N. Onoda)

If A is an An fibration over a regular local ring R, then, by a result of Asanuma, A is stably isomorphic to the polynomial algebra R^[n], i.e., A[m] is isomorphic to R[n+m] for some non negative integer m. There are examples where m need not be zero. A minimal lower bound for this integer m is being investigated. (T. Asanuma and Neena Gupta)

Broad area of my research is "Projective Modules and Complete Intersections". I have been focusing on problems related to the Euler class group. Two papers published in the year 2011-12 involve exploring the relation between the Euler class group of a ring and that of its polynomial extension.

(Mrinal Kanti Das)

Differential Topology:

The notion of double structures were introduced in the theory of Lie groupoids and Lie algebroids by K. Mackenzie. Double structures appear in connection with Poisson Geometry, namely in the context of Poisson groupoids. We have observed that similar double structures also arise in the context of Jacobi groupoids and Jacobi vector bundles. We also observe that the Poissonisation functor can be extended to double structures. The work has been done in collaboration with Neeta Pandey.

(Mahuya Datta)

Operator Theory:

Currently I am studying representation theory of planar algebras, a pictorial invariant for subfactors. We have proved a conjecture of Kevin Walker and Vaughan Jones relating affine representations of subfactor planar algebras to the Drinfeld center of a bimodule category coming from the subfactor.

(Paramita Das)

Probability Theory

Information economics. Moral hazard problems and incentives. Spectral inference. Spectral properties of large dimensional random matrices.
