Venue: SMS seminar room
Speaker: Manas Kar, National Taiwan University in Taiwan
Title: Inverse problems for reconstructing inclusion and identifying unknown parameter

In general, inverse problems are those where one needs to recover the unknown parameter of a system from the knowledge of the external observation. In this talk, I will mainly give an overview of Calder\'on’s inverse problems arising in several linear and nonlinear partial differential equations...

Date/Time: Thursday, February 8, 2018 - 16:00 to 17:00
Venue: Seminar Room, SMS
Speaker: Dr. Shanta Laishram, Indian Statistical Institute, Delhi
Title: Powers in products of terms of Binary Recurrence Sequences

It is known that there are only finitely many perfect powers in non degenerate binary recurrencesequences. However explicitly finding them is an interesting and a difficult problem for binary recurrencesequences. A breakthrough result of Bugeaud, Mignotte and Siksek states that Fibonacci...

Date/Time: Thursday, February 8, 2018 - 14:30 to 15:30
Venue: Seminar Room, SMS
Speaker: Professor Komatsu Takao, Wuhan University
Title: Several identities related to the degenerate Bernoulli polynomials and numbers

In this talk we demonstrate some relations in degenerate Bernoulli polynomials , which may be expressed as a general convolution identity. We also show some properties of hypergeometric degenerate Bernoulli polynomials and numbers.  

Date/Time: Monday, January 22, 2018 - 17:30 to 18:30
Venue: LH-5
Speaker: Professor Kalyan Bidhan Sinha, JNCASR, Bangalore
Title: The Fundamental Theorem of Integral Calculus

In the early days of our learning , most of our knowledge and practice of Integration is based on the Fundamental Theorem of Integral Calculus (FTIC). But the ideas and the intuition of it changes drastically as one tries to move onto higher dimensions or onto more "general sets", leading to new...

Date/Time: Thursday, January 18, 2018 - 15:30 to 17:00
Venue: M-1
Speaker: Prof. T. N. Shorey, NIAS, Bengaluru
Title: Explicit abc-conjecture and its recent applications

Abstract:The well-known abc- conjecture due to Oesterle and Masser in 1985is not explicit. Thus it may not solve an equation completely; it may giveonly bounds for the number of solutions or bounds for the magnitude ofsolutons. With this in mind, Baker in 2004 formulated an explicit versionof...

Date/Time: Monday, January 15, 2018 - 08:00 to Friday, January 19, 2018 - 20:00
Venue: Seminar Room, School of Mathematical Sciences
Date/Time: Friday, January 12, 2018 - 16:30 to 17:30
Venue: LH-5
Speaker: R. Srinivasan, Chennai Mathematical Institute
Title: The framework of quantum probability

We will discuss the general framework of quantum probability as the non-commutative generalization of the classical probability, operations on that and some of the quantum impossibilities. 

Date/Time: Wednesday, January 10, 2018 - 13:30 to 14:30
Venue: Seminar Room, School of Mathematical Sciences
Speaker: Kunal Krishna Mukherjee, IIT Madras
Title: Factoriality of q-deformed Araki-Woods algebras

We discuss factoriality and structural properties of the q-deformed algebras of Hiai. These are type III cousins of the free group factors, extremely complicated objects and even very basic questions about them remain open. Using maximal abelian subalgebras we demonstrate that they are factors...

Date/Time: Friday, December 8, 2017 - 10:30
Venue: Seminar Hall, SMS
Speaker: Santu Pal, SMS, NISER
Title: Cryptanalysis of stream cipher

Abstract: Stream cipher plays an important role in cryptography. The basic component of stream cipher is Linear Feedback Shift Registrar. Here we will discuss about the general construction of a LFSR based stream cipher and the cryptanalysis of stream cipher.

Date/Time: Tuesday, December 5, 2017 - 10:30 to 11:30
Venue: Seminar Room, School of Mathematical Sciences
Speaker: Riddhi Shah, JNU
Title: Dynamics of Distal Actions on Groups

An automorphism T of a locally compact group is said to be distal if the closure of the T-orbit of any nontrivial element stays away from the identity. We discuss some properties of distal actions on groups. We will also relate any distal group with the behaviour of convolution powers of...
