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.

Growth curve model, Applications of Statistics to Industrial quality control, Physics, Sociology,
Agriculture, Education, Fluid mechanics and other natural sciences. Rates of convergence in
Central Limit Theorem (CLT), Law of iterated logarithms (LIL) and Characterization theorems.
