Topics covered in the workshop

Non linear hyperbolic conservation laws play a central role in science and engineering and  form the basis for the mathematical modeling of many physical systems. Their  theoretical and numerical analysis thus plays an important role in applied mathematics and applications. Hyperbolic conservation laws present unique challenges for both theory and numerics as smoothness of their  solution breaks down and produce discontinuities. The main aim of this workshop is to introduce this area  to the young researchers starting from the basics to the advanced level from theoretical as well as computational point of view so that they can  take up this area for their further research.

A Brief Description of the Subject
The development of Algebraic Geometry in the 20th century went through a few salient phases; the first one was dominated by the Italian geometers. This phase was when algebro-geometric techniques were closely linked with topology and analytic geometry and were used in developing the theory of algebraic surfaces. But the shortcoming of this phase was that the intuitive aspects of the geometry was given more importance and there was a neglecting of the key aspects of proofs and rigour as well as analysis of special examples which were needed to support the intuition.  The period 1930-1960 was dominated by the work of Zariski, Weil intended to set right these shortcomings; this culminated in the grand synthesis in the hands of Grothendieck. An immense programme was launched by Grothendieck which introduced tools from commutative algebra into algebraic geometry which afforded a uniform language to handle geometry over characteristic p and characteristic zero. The goal was to create a geometry which synthesized the formal arithmetic aspccts of geometry as well as classical projective geometry. Some of the spectacular successes achieved by algebraic geometry both in its geometric as well as its arithmetic aspects can be directly linked to this grand synthesis initiated by the work of Grothendieck. Just to name a few, Deligne's proof of Weil conjectures, Faltings proof of the finiteness of rational points, Wiles's proof of Fermat's last theorem rely indispensably on this super structure.
The AIS will be directed towards making young researchers in India familiar with the developments in Algebraic Geometry, with special emphasis on Grothendieck's programme. The three week programme is primarily aimed at early researchers in this field to become familiar and users of the tools and techniques in this subject. To acquire a good knowledge of modern algebraic geometry it is essential to see the “local” aspects coming  from Commutative algebra in its interplay in geometry as well as the immense machinery of cohomology. These two themes will be the main ones for the workshop. To give a flavour of the manner in which these tools have lead to fundamental theorems in algebraic geometry, the  final week will stress on some research themes.  A team of active researchers in the field has been invited for this purpose.  The basic reference for this course will be the book by Hartshorne supplemented by books by Mumford, Ueno and others.
Schemes: Sheaves, schemes,  elementary properties, morphisms,  invertible sheaves and bundles, differentials, valuative criterion, Bertini’s theorems,  Lefschetz theorem. Derived functors, cohomology of sheaves, Cech cohomology, Cohomology of projective space, Serre duality, semicontinuity  theoremes , Zariski’s main theorem and connected theorem,  Fulton Lazarsfeld connectedness theorem.

Workshop and International Conference on Automorphic Forms and Number Theory

Venue: KSOM, Kozhikode

30th August - 3rd September, 2013

Objective
Recent developments in various branches of mathematics and physics show an increasing interest in the explicit construction of Jacobi forms, in particular, Jacobi forms of matrix (or, equivalently, lattice) index. This has to do with their appearance in quantum field theory, module spaces of surfaces, infinite dimensional Lie algebras. Though Jacobi forms of matrix index are known since quite long it is only recently that there was an essential breakthrough in the theory. For example, recent work of Gritsenko, Skoruppa, Zagier shows that Jacobi forms can be constructed in a surprisingly explicit way. These constructions in turn are closely related to classical problems in the arithmetic theory of lattices and in the theory of trigonometric polynomials.

For getting interested researchers or graduate students up to date in recent developments we have conducted a 3 days instructional workshop on Jacobi forms of lattice index, followed by a 2 days conference, where participants of the workshop got an opportunity to report on their own research projects for initiating discussions, obtaining feedback or help.

Part 1: Workshop on Jacobi forms of lattice index
Organizers: Prof. M. Manickam, Prof. Ramakrishnan B., Prof. Nils Peter Skoruppa
Lecturers: Hatice Boylan (Istanbul Üniversitesi and Max-Planck-Institute Bonn), Fabien Cléry (University of Siegen), Nils-Peter Skoruppa (University of Siegen and Max-Planck-Institute Bonn)
Overview: The workshop aimed to give a careful and thorough introduction into the theory of Jacobi forms of lattice index with emphasis on explicit constructions, in particular, for low weights and maximal lattices as index. In addition, it showed how Jacobi forms can be used to construct other types of automorphic forms via the so-called additive and multiplicative liftings.
Subjects:
● Basic notions: Lattices, shadows, discriminant modules, definition of Jacobi forms, discussion of the definition, first examples, functorial properties
● Jacobi forms as theta functions: vector valued modular forms, relation between Jacobi forms and vector valued modular forms, dimension formulas
● Explicit constructions of Jacobi forms: Taylor expansion around 0, Theta blocks, invariants of Weil representations
● Maximal lattices as index, explicit description of forms of singular and critical weight and maximal index
● Additive and multiplicative liftings, product expansions

Schedule:
Friday to Sunday: each day 3 lectures of 90 min and 60 minutes for discussions, questions and problem session

A Brief Description of ATM Schools
Advanced Training in Mathematics (ATM) Schools are a joint effort of a large number of mathematicians in the country for training mathematics research scholars and teachers with generous support from the National Board for Higher Mathematics. The programmes are conducted in reputed mathematics departments in Summer and Winter each year. In these Schools, the emphasis is on problems solving and on understanding interrelations of basic subjects in mathematics. At the initial stage, ATM Schools consist of two Annual Foundation Schools (AFSI & II) in algebra, analysis, and topology. At a later stage, Advanced Instructional Schools (AIS) and workshops (ATMW) in all major areas are organised. Several advanced instructional schools (ATML) are organized each year exclusively for young lecturers in colleges and universities.

Advanced Instructional School on Schemes and Cohomology
The AIS was directed towards making young researchers in India familiar with the developments in Algebraic Geometry, with special emphasis on Grothendieck’s programme. The three week programme was primarily aimed at early researchers in this field to become familiar and users of the tools and techniques in this subject. To acquire a good knowledge of modern algebraic geometry it is essential to see the “local” aspects coming from Commutative algebra in its interplay in geometry as well as the immense machinery of cohomology. These two themes were the main ones for the workshop. To give a flavour of the manner in which these tools have lead to fundamental theorems in algebraic geometry, the final week stress on some research themes. A team of active researchers in the field had participated for this purpose.
