Speaker: Dr. Mahabir Prasad Jhanwar, University of Calgary, Canada

Title: Cryptographic Accumulators using Lattices

**Abstract: **Accumulators are cryptographic authentication primitives for verifying set-membership relations. Given a set X of elements, an accumulator can be used to compute an accumulation value, a short secure description Acc(X) of X,...

Date/Time: Thursday, August 28, 2014 - 09:00 to Friday, August 29, 2014 - 17:30

Date/Time: Monday, August 25, 2014 - 11:35 to 12:35

Speaker: G. Priyanga, NISER, Bhubaneswar

Title: Mathematical Modeling

**Abstract:** In this talk, we aim to introduce the process of mathematical modeling using differential equations. Basic compartmental models for spread of infectious diseases (mathematical epidemiology) will be described. In particular, models on *the impact of...*

Date/Time: Friday, August 22, 2014 - 15:45 to 16:45

Speaker: Professor S. G. Dani, T.I.F.R and I.I.T. Bombay

Title: Lattice points in regions of the plane and spaces of higher dimension

**Abstract: **Lattice points contained in regions of the plane, and higher dimensional Euclidean spaces, have been a topic of much study, going back at least to the century-old work of Minkowski. In recent decades there have...

Date/Time: Tuesday, August 19, 2014 - 11:30 to 12:30

Date/Time: Monday, August 18, 2014 - 11:30 to 12:30

Date/Time: Monday, August 11, 2014 - 11:35 to 12:35

Speaker: S Bibek Sankar, NISER, Bhubaneswar

**Abstract:** In this talk, we try to understand elements of chaos theory in dynamical systems numerically and graphically. We also try to understand the the various properties like period doubling and chaos of the famous Logistic Map. Along with it some other less known maps, the...

Date/Time: Thursday, August 7, 2014 - 16:00 to 17:00

Speaker: Shalabh, Department of Mathematics & Statistics, Indian Institute of Technology, Kanpur

Title: Measurement Error Models - An Introduction

**Abstract:** All the statistical analysis assumes that all the measurements are obtained correctly. In practice, the observations can be correctly obtained only in controlled environment and this assumption is violated in many real life data. Instead of the true value of the...

Date/Time: Monday, August 4, 2014 - 11:35 to 12:35

Speaker: Subham Giridhar, SMS, NISER

Title: Elementary Number Theory

**Abstract**: In this talk, using the basics of the Arithmetic that was learned in school, some of the elementary theorems of Number theory will be proven and also a flavor of RSA encryption will be given using the theory discussed...
