One was the closure of our collaborative middle school educational programmes by the Madhya Pradesh government in July 2002 The second was the bifurcation of Eklavya into two autonomous units - a 'school education and publication' group and a'rural development'group.The latter was registered as a new society on August 1 1, 2003 as the Samavesh Society for Development and Governance. -
16 February 2016 Prof. M. Jagadesh Kumar Vice Chancellor
16 February 2016 Prof. M. Jagadesh Kumar Vice Chancellor Jawaharlal Nehru University New Delhi-110 067, India Dear Prof. Kumar, We are writing, as a group of academics, to express our deep disappointment with your actions in the event leading up to the arrest of several students last week. We understand that last Tuesday, a student group organized a rally to commemorate the death anniversary of Afzal Guru. The police alleges that some of the students voiced controversial opinions. The police then proceeded to arrest the president of the JNU Students Union, Kanhaiya Kumar, and charged him with sedition. This has been followed by a number of further arrests. What is most disturbing is that the JNU administration appears to have defended and aided these repressive actions by the police, rather than defending the students who were involved in a non-violent activity. The arrest of the president of the JNUSU is especially troublesome since he was not even an organizer of the rally but merely present to express his solidarity. However, even as far the organizers and the speakers at the event are concerned, we hope that you recognize that expressing controversial views in a peaceful forum cannot be equated with sedition. For example, many people believe that Afzal Guru was let down by a lack of appropriate legal representation in his trial, and that his execution was therefore a grave miscarriage of justice. One may agree or disagree with this viewpoint — and, indeed, signatories to this letter hold different positions — but we are unanimous that students should have the right to freely discuss this issue. -

It is an autonomous institute fully funded by the Department of Atomic Energy, Government of India. Till October 10, 2000 the Institute was known as Mehta Research Institute of Mathematics and Mathematical Physics (MRI) after which it was renamed as Harish-Chandra Research Institute (HRI) after the internationally acclaimed mathematician, late Prof Harish-Chandra. The Institute started with efforts of Dr. B. N. Prasad, a mathematician at the University of Allahabad with initial support from the B. S. Mehta Trust, Kolkata. Dr. Prasad was succeeded in January 1966 by Dr. S. R. Sinha, also of Allahabad University. He was followed by Prof. P. L. Bhatnagar as the first formal Director. After an interim period in January 1983, Prof. S. S. Shrikhande joined as the next Director of the Institute. During his tenure the dialogue with the Department of Atomic Energy (DAE) entered into decisive stage and a review committee was constituted by the DAE to examine the Institutes fu- ture. In 1985 N. D. Tiwari, the then Chief Minister of Uttar Pradesh, agreed to provide sufficient land for the Institute and the DAE promised financial sup- port for meeting both the recurring and non-recurring expenditure. -

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. -

Star Products from Commutative String Theory
hep-th/0108072 TIFR/TH/01-28 Star Products from Commutative String Theory Sunil Mukhi Tata Institute of Fundamental Research, Homi Bhabha Rd, Mumbai 400 005, India ABSTRACT A boundary-state computation is performed to obtain derivative corrections to the Chern-Simons coupling between a p-brane and the RR gauge potential Cp−3. We work to quadratic order in the gauge field strength F , but all orders in derivatives. In a certain limit, which requires the presence of a constant B-field background, it is found that these corrections neatly sum up into the product of (commutative) gauge fields. The result ∗2 is in agreement with a recent prediction using noncommutativity. arXiv:hep-th/0108072v1 10 Aug 2001 August 2001 Introduction In a recent paper[1] it was shown that the noncommutative formulation of open-string theory can actually give detailed information about ordinary commutative string theory. Once open Wilson lines are included in the noncommutative action, one has exact equality of commutative and noncommutative actions including all α′ corrections on both sides. As a result, a lot of information about α′ corrections on the commutative side is encoded in the lowest-order term (Chern-Simons or DBI) on the noncommutative side, and can be extracted explicitly. The predictions of Ref.[1] were tested against several boundary-state computations in commutative open-string theory performed in Ref.[2], and impressive agreement was found. The latter calculations were restricted to low-derivative orders, largely because the boundary-state computation becomes rather tedious when we go to high derivative order. However, in some specific cases, particularly when focusing on Chern-Simons couplings in the Seiberg-Witten limit[3], the predictions from noncommutativity in Ref.[1] are simple and elegant to all derivative orders as long as we work with weak field strengths (quadratic order in F ). -
