09:15 to 09:30 -- Opening Remarks
09:30 to 10:30 N. Mukunda Noether’s Theorem in Classical Dynamics : Continuous Symmetries and Conservation Laws for physical systems

A pedagogical account of the deep interrelations between continuous symmetries of physical systems described by Action Principles , the associated Constants of Motion, and their role as generators of canonical transformations, will be presented.The application to the theory of Constrained Dynamical Systems as developed by Dirac will also be described.

10:45 to 11:45 Sudesh Khanduja Origin and Development of Valuation Theory

Emmy Noether played a great role in the development of valuation theory since its inception. She was the first one to provide an axiomatic base for Dedekind rings; she called them F unf Axiome-Ringe (five axiom rings). She actively participated together with Richard Brauer and Helmut Hasse in the proof of the local global principle for central simple algebras. We go down the memory lane and discuss some significant contributions to Valuation Theory by K ursch`ak, Ostrowski,Noether, Hasse and others.

12:45 to 14:00 -- Lunch
14:00 to 15:00 Lakhsmanan Muthusamy Interplay of symmetries and other integrability quantifiers in finite dimensional nonlinear dynamical systems

In my talk, I will establish an important interlink between Noether symmetries, Lie point symmetries, contact symmetries, lambda symmetries, adjoint symmetries, null form, inegrating factors, Darboux polynomials, Jacobi last multipliers and generalized lambda symmetries through connection with Prelle - Singer method. I will show the relationship for two, three and nth order nonlinear differential equations.

15:15 to 16:15 Rohini Godbole Noether's theorem and particle physics

In this talk I will tell the story of the role played by Noether's Theorem in arriving at our current knowledge of quarks and leptons as elementary constituents of matter and the nature of the fundamental interactions among them. I will also like to comment on Emmy Noether's achievements from the point of view of a theoretical physicist who happens to be a woman!

10:00 to 11:00 Joseph Samuel Noether's theorems and their growing physical relevance

Noether's work on symmetries and conservation laws was far ahead of its time. As a result, Noether's theorems initially had little impact in the physics community. In those days, it was not widely appreciated that the laws of nature were best expressed as variational principles. With the growing realisation that variational principles provide an economical restatement of Nature's Laws and symmetries, the power and generality of Noether's work came to be appreciated. When the signifance of Noether's theorems was finally understood in the middle of the last century, they were seen to contain seeds of many ideas which dominate modern physics: conserved currents, gauge invariance, symplectic geometry, Dirac's theory of contraints and the elusive nature of gravitational energy.

11:15 to 12:30 Ravi Rao Emmy Noether in Erlangen and Göttingen

We give an overview of Emmy Noether's seminal works; and her contribution to the birth of modern algebra. We also give an indication of its influence in present day research.
   
12:30 to 14:00 -- Lunch
14:00 to 15:00 Subhro Bhattacharya Symmetries and Condensed Matter physics

Noether's formulation of invariance of action (describing the system) under symmetry transformations and understanding the conserved currents (Noether currents) play an important role in describing condensed matter systems. Only recently, we have encountered prototypical systems where interesting physics can emerge even in absence of symmetries. I will give a general outline of how Noether's work have shaped thinking about condensed matter phases in terms of symmetries and also about recent developments where such ideas partially break down in an important way.
