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”. -
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. -

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. Four students were awarded M.Sc. by Research, and two students have submitted their master’s theses under the supervision of our faculty. -

Conformal $ N $-Point Functions in Momentum Space
Conformal n-point functions in momentum space Adam Bzowski∗ Department of Physics and Astronomy, Uppsala University, 751 08 Uppsala, Sweden. Paul McFaddeny School of Mathematics, Statistics & Physics, Newcastle University, Newcastle NE1 7RU, U.K. Kostas Skenderisz STAG Research Center & Mathematical Sciences, University of Southampton, Highfield, Southampton SO17 1BJ, U.K. We present a Feynman integral representation for the general momentum-space scalar n-point function in any conformal field theory. This representation solves the conformal Ward identities and features an arbitrary function of n(n − 3)=2 variables which play the role of momentum-space conformal cross-ratios. It involves (n − 1)(n − 2)=2 integrations over momenta, with the momenta running over the edges of an (n − 1)-simplex. We provide the details in the simplest non-trivial case (4-point functions), and for this case we identify values of the operator and spacetime dimensions for which singularities arise leading to anomalies and beta functions, and discuss several illustrative examples from perturbative quantum field theory and holography. I. MOTIVATION recent efforts, all the necessary prerequisites are now in place. Firstly, the momentum-space 3-point functions The structure of correlation functions in a conformal of general scalar and tensorial operators are known, in- field theory (CFT) is highly constrained by conformal cluding the cases where anomalies and beta functions symmetry. It has been known since the work of Polyakov arise as a result of renormalization [34{46]. Secondly, [1,2] that the most general 4-point function of scalar momentum-space studies of the 4-point function have yielded special classes of solutions to the conformal Ward primary operators ∆j , each of dimension ∆j, takes the form O identities [15, 32, 47{51]. -
