Title: A CONSTRUCTION OF NON-KAHLER COMPLEX MANIFOLDS

The compact torus S1 × S1 has a structure of Riemann surfaceand therefore is a complex projective manifold. On product of odd dimensionalspheres S2p+1 × S2q+1 with p > 0 or q > 0, complex structures were obtainedby H. Hopf (1948) and Calabi-Eckmann (1953). These complex manifolds areone of...

Title: Algebraic Constructions of Message Authentication Codes

Abstract:Message Authentication Code  (MAC) is a symmetric key cryptographic primitive to ensure data authentication. Traditionally, MACs are constructed using block ciphers. In this talk, we review how MACs can be constructed using Algebraic Structures and analyze their strength against related...

Speaker: Atreyee Bhattacharya, RamaKrishna Mission Vivekananda University
Title: An ODE associated to the Ricci flow

Ricci flow and associated techniques have played pivotal roles in solving some long-standing open problems in Geometry and Topology in recent times.  In this talk we will discuss some properties of an ODE related to the evolution of curvature along the Ricci flow and my recent results in this...

Speaker: Dr. Prem Prakash Pandey, HRI, Allahabad
Title: Square free values of polynomials

It is conjectured that all separable polynomials with integers coefficients, under some local conditions, take infinitely many (in fact positive density of) square free values on integer arguments. But not a single polynomial of degree greater than $3$ is proven to exhibit this property. We...
