IISER, Pune | Anupam Singh | How to reach IISER |

Aim :

The aim of this workshop is to motivate students to take up Mathematics for research. We have invited eminent mathematicians
of our country to speak in this workshop. We also want to create awareness about Mathematics education, in general. Thus, keeping
this in mind we have requested each mathematician to be available in the afternoon to interact with audience.

Date and Time | Speaker | Title | Abstract |
---|---|---|---|

27 July 2009, 10:00 AM | Inauguration | ||

27 July 2009, 10:30 AM | Prof. Sridharan, CMI Chennai | Enumeration of some combinatorial patterns in Ancient India | Not received yet |

27 July 2009, 11:45 AM | Prof. Raja Sridharan, TIFR Mumbai | Pell's Equation | We will consider the Equation of Pell from a historical context and outline the historical contributions of the Indian Mathematicians to this topic and relate it to more recent Developments like the Units of Quadratic Fields, Pfister forms etc. |

28 July 2009, 10:00 Noon | Prof. P. N. Srikanth, TIFR Bangalore | Partial Differential Equations: why study them | Not recieved yet |

28 July 2009, 11:30 AM | Prof. D. Thakur, University of Arizona | Good Approximations | Not received yet |

29 July 2009, 10:00 AM | Prof. Siddhartha Gadgil, IISc Bangalore | One can not hear the shape of a drum | The notes produced by a drum depend on its shape and size. The isospectral problem asks whether two drums of different shapes can produce the same set of notes. In this talk, we present a simple example of such a pairs of drums (due to Buser, Conway, Doyle and Semmler). We also discuss some related mathematics, in particular the so called reflection principle. |

29 July 2009, 11:30 AM | Prof. C. S. Dalawat, HRI Allahabad | p-adic numbers | Around a hundred years ago, a new number system was discovered. it is called the system of p-adic numbers, and there is one such system for every prime number p. We will give an elementary introduction to these numbers and show what they good for. |

30 July 2009, 10:00 AM | Prof. Siddhartha Bhattacharya, TIFR Mumbai | Perron-Frobenius theorem | In this talk we will consider large matrices with strictly positive entries. We will prove a result about eigenvalues and eigenvectors of such matrices, and discuss its application in internet search engines and tournaments. |

30 July 2009, 11:30 AM | Prof. D. Dhar, TIFR Mumbai | Some Enumeration Problems from Statistical Physics | In this talk, I will discuss how the main problem in equilibrium statistical physics can be reduced to that of finding the number of different states available to a given system having energy in a given range E_1 < E < E_2. We start by enumerating the number of random walks of N steps on a line, or on a square lattice. The number of walks having a specified endpoint R has many applications in the theory of diffusion. And it introduces the technique of Generating Functions for enumeration problems. More complicated problems are like self-avoiding walks. We discuss upper and lower bounds for the number of self-avoiding walks, and introduce the computer algorithms for enumeraion. Finally, I discuss the number of partitions of an integer N to illustrate the power of the method of generating functions. Some harder problems will be listed, but left as home-wok problems. |

31 July 2009, 10 AM | Prof. N. Raja, TIFR Mumbai | The Axiomatic Technique in Logic & Mathematics | This talk will provide a very short introduction to the elements of the axiomatic technique, and some of its associated notions such as consistency, completeness, categoricity, and independence. |

31 July 2009, 11:30 AM | Prof. R. Sujatha, TIFR Mumbai | The Mysteries of the prime numbers | Not received yet |

1 August 2009, 9:30 AM | Prof. Ramanan, CMI, Chennai | Symmetries in every day life and in the Sciences | Not received yet |

1 August 2009, 11:00 AM | Prof. H. Bhate | Fourier Analysis on Groups | Not received yet |

1 August 2009, 12:00 Noon | Prof. S. A. Katre, Pune University | The Mobius Function | In this talk we shall discuss the Mobius function, its properties, its importance in the theory of arithmetic functions and its application to factoring polynomials of the type x^n-y^n over integers. |
