Seminar on October 29 - Tirthankar Bhattacharyya

Spectral and Complete Spectral Sets

Prof. Tirthankar Bhattacharyya

Indian Institute of Science, Bangalore


Time: 12 to 1 pm, Tuesday, October 29, 2013
Venue: CR 201

Abstract: A compact set \(K\) in \({\Bbb C}^n\) is a spectral set for a commuting tuple \(T=(T_1,\dots,T_n)\) of bounded Hilbert space operators if the joint spectrum of \(T\) is contained in \(K\) and if the von Neumann-type inequality \[ ||r(T_1,\dots,T_n)|| \le \sup\{ |r(z)| : z\in K\} \] holds for all rational functions \(r\) in \(Rat(K)\). If the corresponding inequality holds even for every \(m\times m\) matrix \(r=(r_{ij})\) with entries in \(Rat(K)\) then \(K\) is called a complete spectral set for \(T\). By a result of Arveson, \(K\) is a complete spectral set for \(T\) if and only if \(T\) possesses a normal boundary dilation over \(K\). For nice domains in \(\Bbb C\), such as the unit disc or annulus, the conditions of being spectral and completely spectral are equivalent. In the lecture we start with the classical theory and try to present some more recent positive and negative results on one and several variable spectral sets.

Seminar on October 10 - Sutanu Roy

Title: Associative twisted tensor product of C*-algebras
Speaker: Sutanu Roy, University of Goettingen

Date: October 10


Time & Venue: 12-1 pm, CR 204 (2nd Floor, B Wing)


Abstract: In this talk, we shall carry forward the notion of quasitriangular quantum groups, introduced by Drinfeld, in Hopf algebraic to C*-algebraic framework. Then we show that the coaction category of C*-algebras over a quasitriangular quantum group is monoidal.

Seminar on September 25 - Abhishek Ranjan



Title:              Arbitrage Structure and Finite Date Model with Financial Restriction
Speaker:       Dr Abhishek Ranjan
Department of Applied Mathematics
Université Paris 1 Panthéon Sorbonne, France

Time:               2 pm, Wednesday, September 25, 2013.
Venue:             TBA
Abstract:         We consider a (T+1)-date model of a financial exchange economy with finitely many agents having non-ordered preferences and portfolio constraints. There is a market for physical commodities for every state today and in the future, and financial transfers across time and states are allowed by means of finitely many nominal or numeraire assets. We examine the properties of the financial structure F and the set of its (limited) arbitrage-free prices QF. The set of arbitrage-free prices is shown to be a convex cone under a sufficient condition that holds in particular for short lived assets. Furthermore, we provide examples of equivalent financial structures F and F’ such that QF is a convex cone, but QF’ is neither convex nor a cone. At the end, we provide several existence results of equilibrium in a financial exchange economy for which portfolios are either defined by linear constraints or a convex set extending the framework of unconstrained case by Cass (1984, 2006), Werner (1985), Duffie (1987), Gaenakopolos and Polemarchakis (1997), framework of linear equality constraints by Balasko et al. (1990) and framework of 2-date by Cornet and Gopalan (2007), Aouani and Cornet (2011, 2013).

About the Speaker:   Dr Ranjan completed his PhD from the Paris School of Economics and Université Paris 1 Panthéon Sorbonne in 2012. His research interests are in Applied Mathematics, General Equilibrium Models, Financial Economics, and Decision Under Uncertainty.

Seminar on September 24 - Vijay Patankar



Congruences between Modular Forms and p-Adic Families of Modular Forms
(from Ramanujan to Hida)

Speaker:       Dr Vijay Patankar
                         International Institute of Information Technology, Bangalore
Time:               3 pm, Tuesday, September 24, 2013.
Venue:            TBA

Abstract:  In this expository talk, we will give an introduction to congruences between modular forms as first observed by Ramanujan and how that has led to p-adic families of modular forms. 

Among many other things, Ramanujan studied certain natural arithmetic functions such as the Partition function and the Sum of Divisors function.  In 1916, Ramanujan in his paper On certain arithmetical functions, observed certain congruences between distinct arithmetic functions and hence between the generating functions associated to them (which are in fact modular forms). In 1967, Serre interpreted these congruences in terms of Galois representations and conjectured the existence of Galois representations associated to modular forms (proved by Deligne 1968). In 1972, Serre constructed a p-adic family of Eisenstein forms. In 1986, Hida constructed p-adic families of cusp-forms and the associated p-adic families of Galois representations.

All these developments were essential tools for Andrew Wiles' proof of Fermat's Last Theorem. 

About the Speaker: Dr Patankar obtained his PhD from the University of Toronto in 2005. He has held positions at the Cold Spring Harbor Laboratory (New York), Microsoft Research India (Bangalore), Bhaskaracharya Pratishthana (Pune) and Indian Statistical Institute (Chennai). His research interests are in Number Theory, Algebraic Complexity Theory and Cryptography.

Minor in Mathematics Form

Applications for the Maths Minor are closed. Results will be out shortly!

Minor in Mathematics Announcement

Undergraduate students of Shiv Nadar University who are not majoring in Mathematics have the option to take a Minor in Mathematics. A Minor in Mathematics can serve two distinct functions (apart from enjoying the beauty of the subject!):
  • Acquiring the academic background for higher studies in Mathematics.
  • Acquiring modelling and computational skills for applications of Mathematics in other disciplines or in industry.
Academic Requirements:

You have to acquire a minimum of 27 credits from the University Wide Elective (UWE) courses offered by the Department of Mathematics. These credits must satisfy the following minimum requirements:
  1. Three courses from Group A for a total of 12 credits: MAT 101 (Calculus I), MAT 240 (Algebra I), MAT 260 (Linear Algebra), MAT 280 (Numerical Analysis I), MAT 284 (Probability & Statistics).
  2. One course from Group B (3 credits): MAT 199, 299, 399, 499 (Projects).
  3. Remainder from any other UWE courses offered by the Department of Mathematics.
  4. The above is subject to the further requirement that a course should not count towards both Major and Minor requirements.
  5. The credit requirement may be lowered to 23 credits for majors which already have a significant component of compulsory Mathematics courses.
The Undergraduate Advisor for Mathematics will help you work out an appropriate choice of courses depending on your interests and background.

How to Apply:
  1. For the 2013 session, there are 20 seats available for a Minor in Mathematics.
  2. You are eligible to apply for the Minor if you have already earned or are currently enrolled in at least 3 credits from courses offered by the Department of Mathematics, and if your GPA from these courses is at least 6.
  3. Eligible applicants will be interviewed, and admission to the Minor will be determined by the results of that interview. The probable interview dates are April 29 and 30.
  4. You can apply by filling out the online form before 5pm on April 26. (Click to go to the online form.)
  5. For further details please contact the UG Advisor for Mathematics, Amber Habib. You can meet him during his office hours or send an email to amber.habib@snu.edu.in to make an enquiry or seek an appointment.
  6. Please note that you must take admission for the Minor as described here. It is not enough to merely take adequate credits on your own. 
Other Information:
  1. Once admitted to the Minor in Mathematics, you will select courses for the Minor in consultation with the UG Advisor for Mathematics.
  2. You must sign up for the Minor before the end of your 6th semester. However, it is advisable to do so earlier so that there is sufficient time to plan your courses. The best time is during your 3rd or 4th semesters.
  3. If you fail to complete the Minor during your first 4 years, you may have to spend an extra semester to complete it. If you do so, any scholarship or fee waiver you were granted for your regular course of study will lapse and you will have to pay the full fees for the extra period.
  4. You may of course enroll for UWE courses offered by the Department without being admitted to the Minor. However, students enrolled for the Minor will have priority while registering for these courses. The Department will also do its best to schedule courses so that Minor students will be able to complete their requirements.
