Complex Multiplication and the Hodge Conjecture

There are certain special complex tori that have "complex multiplication". The study of these tori essentially begins with the work of Gauss on definite binary quadratic forms and Abel/Jacobi on the associated complex tori. Attempting to extend this theory to higher dimensions, this gives questions that are test cases for the Hodge conjecture. We will talk about past and recent work on Complex Multiplication.

Title: Introduction to nonlocal equations

In this talk I would introduce a family of integro-differential operators, known as fractional Laplacian, and give an overview of its properties, notion of solution etc. Then we would consider few specific classes of problems involving fractional Laplacian and discuss some qualitative properties of the solution.

Nitin Nitsure

I am an algebraic geometer, specializing in the theory of vector bundles and related objects, and their moduli spaces. I have a construction of the moduli spaces for Hitchin pairs, logarithmic connections and D modules, and recently also for rank 2 unstable bundles on curves. I have proved results about the topology of these spaces, and also on the topology of conic and quadric bundles and related characteristic classes. Besides algebraic geometry and topology, I am interested in mathematical logic and the foundations of mathematics, as well as in mathematical physics. I have a special interest in mathematics education at the higher level. Currently, I am a Member of the National Board for Higher Mathematics of the Government of India.

Title: Noether's conservation theorem and moment maps

Abstract: In this, I will first explain Emmy Noether's famous conservation theorem for Hamiltonian mechanics, and then talk about its modern improved version due to Souriau - the moment map. I will illustrate it with some examples.

Sachi Srivastava

Dr Sachi Srivastava is currently an Associate Professor of Mathematics at the University of Delhi. After obtaining her Bachelors and Masters degrees from Lady Shri Ram College, University of Delhi she moved to the University of Oxford, UK in 1998 to study for a DPhil in Mathematics on a Commonwealth Scholarship. After doing her post-doctoral work at the Indian Institute of Science, Bangalore and a teaching stint at Lady Shri Ram College she joined the University of Delhi as a faculty member in 2007.
Dr Srivastava’s research interests fall under the general umbrella of operator theory and Operator algebras, with a focus on Operator semigroups and abstract Cauchy problems. She has co-authored a book ”Theory of Semigroups and Applications” and has several peer reviewed journal articles to her name. She currently has six doctoral students and has supervised six M Phil thesis in different areas of operator theory at the University of Delhi. She is actively involved in IWM activities and serves on the executive committee of this NBHM sponsored initiative. She was awarded a grant from the London Mathematical Society under Scheme 2 to visit the UK, June 2015 and was a recipient of the Commonwealth Research Award Association of Commonwealth Universities, UK, 1998.

Title: An introduction to Operator Semigroups

Abstract: In this mainly expository talk we will give a brief introduction to the theory of Operator Semigroups and glimpse a few current areas of research.

Title: Statistical Data Mining — Challenges and Scope

Abstract: The talk will highlight some challenges of real data and limitations of conventional methods of statistical analysis. Scope of some data-driven approaches to statistical leaning and modeling with applications in Bioinformatics, Drug Designing and Finance will be discussed.  

Swagata Sarkar

My interest in mathematics was first kindled by puzzles, when I was primary school. I later went on to do my Bachelors’ and Masters’ in mathematics from Delhi University, and my Ph.D. from the Institute of Mathematical Sciences, Chennai. At present, I am affiliated to the UM-DAE CEBS, Mumbai.

Title: Careers in Mathematics

Abstract: In 2016, “The U.S. News” ranked the job of a mathematician to be the most satisfactory job in the world. But who exactly is a “mathematician” - and what can be his/her job? We will discuss some of the obvious, and some not-so-obvious, answers to these questions during today’s talk.

Riddhi Shah

Riddhi Shah is Professor of Mathematics at the School of Physical Sciences (SPS), Jawaharlal Nehru University (JNU), New Delhi. She is the Chairperson of the Executive Committee of Indian Women and Mathematics (IWM) initiative. Her research interests include dynamics of group actions and probabilities on groups. Riddhi Shah studied at St Xavier's College, Gujarat University for a BSc degree in Mathematics. After receiving an MSc degree in Mathematics from IIT Bombay, she joined the Tata Institute of Fundamental Research (TIFR), Mumbai for her doctoral studies and completed a doctorate in 1991. She was a faculty member at TIFR, Mumbai from 1990 until 2007, when she joined SPS, JNU. She has visited several institutions abroad with post-doctoral fellowships. Riddhi Shah was a gold medallist during her undergraduate degree in Gujarat University. She has many publications in reputed international journals. She was awarded the Indian National Science Academy’s medal for young scientists in 1995, the Alexander von Humboldt Fellowship in 1997, CNRS  fellowship in 2003 and an Invitation Fellowship in 2004 from the Japan Society for Promotion of Science (JSPS).

Title: Dynamics Distal Maps

Abstract: Distal maps were introduced by David Hilbert on compact spaces to study non-ergodic maps. A homeomorphism T on a topological space X is said to be distal if the closure of the double T-orbit of (x, y) does not intersect the diagonal in X x X unless x=y. For an automorphism T of a locally compact group G, this definition is equivalent to the following: T is distal if the T-orbit of any x in G does not go close to the identity e unless x=e. (A T-orbit of x is a set consisting all elements of the form S(x), where S is an nth power of T for an integer n). We study some properties of distal maps, especially distal automorphisms on locally compact groups. We also study the behaviour of orbits of distal maps.
