Annual Report THE INSTITUTE OF MATHEMATICAL SCIENCES C. I. T. Campus, Taramani, Chennai - 600 113. ANNUAL REPORT Apr 2003 - Mar 2004 Telegram: MATSCIENCE Fax: +91-44-2254 1586 Telephone: +91-44-2254 2398, 2254 1856, 2254 2588, 2254 1049, 2254 2050 e-mail: offi[email protected] ii Foreword I am pleased to present the progress made by the Institute during 2003-2004 in its many sub-disciplines and note the distinctive achievements of the members of the Institute. As usual, 2003-2004 was an academically productive year in terms of scientific publications and scientific meetings. The Institute conducted the “Fifth SERC School on the Physics of Disordered Systems”; a two day meeting on “Operator Algebras” and the “third IMSc Update Meeting: Automata and Verification”. The Institute co-sponsored the conference on “Geometry Inspired by Physics”; the “Confer- ence in Analytic Number Theory”; the fifth “International Conference on General Relativity and Cosmology” held at Cochin and the discussion meeting on “Field-theoretic aspects of gravity-IV” held at Pelling, Sikkim. The Institute faculty participated in full strength in the AMS conference in Bangalore. The NBHM Nurture Programme, The Subhashis Nag Memorial Lecture and The Institute Seminar Week have become an annual feature. This year’s Nag Memorial Lecture was delivered by Prof. Ashoke Sen from the Harish-Chandra Research Institute, Allahabad. The Institute has also participated in several national and international collaborative projects: the project on “Automata and concurrency: Syntactic methods for verification”, the joint project of IMSc, C-DAC and DST to bring out CD-ROMS on “The life and works of Srini- vasa Ramanujan”, the Xth plan project “Indian Lattice Gauge Theory Initiative (ILGTI)”, the “India-based neutrino observatory” project, the DRDO project on “Novel materials for applications in molecular electronics and energy storage devices” the DFG-INSA project on “The spectral theory of Schr¨odinger operators”, and the Indo-US project on “Studies in quantum statistics”. The cluster computer being built under the ILGTI project has already reached a performance of 539 GFlops with only 81 nodes and is expected to compete for a slot in the top 500 supercomputers in the world. (I am pleased to note that the full cluster posted a performance of 959 GFlops getting a world rank of 257 in June 2004.) This report has been compiled through the efforts of a committee consisting of Drs. G. Date, Parameswaran Sankaran, C. R. Subramanian and Mr. Paul Pandian (Librarian) together with secretarial assistance from Ms. Usha Devi. The photographs have been contributed by administration and Drs. Rahul Basu, N. D. Hari Dass, Gautam Menon, M. V. N. Murthy. I owe my gratitude to all of them. I look forward to another year full of distinctive achievements for the Institute. April, 2004 R.

Classical phases of (0 + 1) dimensional unitary matrix models can be characterised by free Fermi droplets in two dimensions. We quantise these droplets and find that the modes satisfy an abelian Kac-Moody algebra. The Hilbert spaces H+ and H− associated with the upper and lower free Fermi surfaces of a droplet admit a Young diagram basis in which the phase space Hamiltonian is diagonal with eigenvalue, in the large N limit, equal to the quadratic Casimir of u(N). We establish an exact mapping between states in H± and geometries of droplets. In particular, coherent states in H± correspond to classical deformation of upper and lower Fermi surfaces. We prove that correlation between two coherent states in H± is equal to the chiral and anti-chiral partition function of 2d Yang-Mills theory on a cylinder. Using the fact that the full Hilbert space H+ ⊗ H− admits a composite basis, we show that correlation between two classical droplet geometries is equal to the full U(N) Yang-Mills partition function on cylinder.

  • Mathematical Physics and String Theory
    TIFR Annual Report 2001-02 THEORETICAL PHYSICS String Theory and Mathematical Physics Tachyon Condensation and Black Hole Entropy Condensation of tahcyons in closed string theory was analyzed and its connection with the computation of the black hole entropy was pointed out. The entropy computed in this manner was found to be in precise agreement with the the Bekenstein-Hawking Entropy. [Atish Dabholkar] Tachyon Potential and C-function A tachyon potential with the appropriate critical points was proposed in terms of an effective c-function of the worldsheet theory and it was determined as a solution of certain integrable equations. [Atish Dabholkar and C. Vafa of Harvard University] D-branes in PP-wave Backgrounds Dirichlet branes in the background of a PP wave were constructed and the open string spectrum was in agreement with the gauge theory spectrum. [Atish Dabholkar and Sharoukh Parvizi] Loop Equation and Wilson Line Correlators in Non-commutative Gauge Theories Loop equations for correlators of Wilson line operators in non-commutative gauge theories were derived. Unlike what happens for closed Wilson loops, the joining term survives in the planar equations. This fact was used to obtain a NEW loop equation which relates the correlation function of an arbitrary number of Wilson lines to a set of closed Wilson loops, obtained by joining the individual Wilson lines together by a series of well-defined cutting and joining manipulations. For closed loops, we showed that the non-planar contributions do not have a smooth limit in the limit of vanishing non-commutativity and hence the equations do not reduce to their commutative counterparts [Avinash Dhar and Y.

    THE INSTITUTE OF MATHEMATICAL SCIENCES C. I. T. Campus, Taramani, Chennai - 600 113. ANNUAL REPORT Apr 2015 - Mar 2016 Telegram: MATSCIENCE Telephone: +91-44-22543100,22541856 Fax:+91-44-22541586 Website: http://www.imsc.res.in/ e-mail: offi[email protected] Foreword The Institute of Mathematical Sciences, Chennai has completed 53 years and I am pleased to present the annual report for 2015-2016 and note the strength of the institute and the distinctive achievements of its members. Our PhD students strength is around 170, and our post-doctoral student strength is presently 59. We are very pleased to note that an increasing number of students in the country are ben- efiting from our outreach programmes (for instance, Enriching Mathematics Education, FACETS 2015, Physics Training and Talent Search Workshop) and we are proud of the efforts of our faculty, both at an individual and at institutional level in this regard. IMSc has started a monograph series last year, with a plan to publish at least one book every year. A book entitled “Problems in the Theory of Modular Forms” as ‘IMSc Lecture Notes - 1’ has been published this year Academic productivity of the members of the Institute has remained high. There were several significant publications reported in national and international journals and our faculty have authored a few books as well. Five students were awarded Ph.D., and three students have submitted their Ph.D. theses.

    The Institute of Mathematical Sciences Annual Report & Audited Statement of Accounts 1 March 2019- April 2020 The Institute of Mathematical Sciences Chennai Annual Report and Audited Statement of Accounts April 2019 - March 2020 Telephone: +91-44-2254 3100, 2254 1856 Website: https://www.imsc.res.in/ Fax: +91-44-2254 1586 DID No.: +91-44-2254 3xxx(xxx=extension) 2 Director’s Note Director’s Note I am happy to present the annual report of the Institute for 2019-2020 and put forth the distinctive achievements of its members during the year along with a perspective for the future. During the period April 2019 - March 2020, there were 144 students pursuing their PhD and 42 scholars pursuing their post-doctoral programme at IMSc. Spread through this period, the Institute organized or co-sponsored several workshops and conferences. The First IMSc discussion meeting on extreme QCD matter held during September 16 - 21, 2019 brought together senior scientists to deliver a set of pedagogic lectures on the current state-of-the-art, open problems and challenges in the area of hot and dense QCD matter. The annual meeting of the International Pulsar Timing Array (IPTA) was organized during June 10 - 21, 2019 by its Indian arm, of which IMSc is a part. An NCM sponsored workshop on Combinatorial Models for Representation Theory was organised in IMSc during November 4 - 16, 2019 and saw active participation from Ph.D students and postdocs from across the country. An ACM-India Summer School on Graphs and Graph Algorithms and a meeting on Recent Trends in Algorithms were both organised during the year.
