- Field Theory: Ist week by Prof. S. A. Katre
- Field Extensions and Examples. Algebraic and transcendental elements. Minimal polynomial. Degree of a field extension. Finite and infinite extensions. Simple extensions. Rationalising the denominator.
- Transitivity of finite/algebraic extensions. Compositum of two fields. Algebraically closed fields. Uncountably many algebraically closed subfields of the field of complex numbers
- Ruler and Compass constructions (in brief), Regular polygons. Squaring the circle etc.
- Existence of a splitting field of a polynomial.
- Symmetric polynomials. Newton’s theorem.
- Fundamental Theorem of Algebra using symmetric polynomials. Luroth’s theorem (Covered by Prof. Avinash Sathaye in a special lecture)
- Field Theory: IInd week by Prof. B. N. Waphare
In my lecture series we studied separable and inseparable extensions. An algebraic extension can be achieved in two stages: first, separable extension and then purely inseparable extension. The degree of a finite purely inseparable extension is a power of the characteristic of the field . The characterization of perfect fields and normal extensions are studied. The multiplicative group of a finite field is cyclic and determination of all subfields of a finite field are taken into consideration.
- Field Theory: IIIrd week by Prof. Parvati Shastri
Lecture 1. Galois extensions, equivalent conditions, examples, Galois group of quadratic, bi-quadratic extensions and extensions like Q(3√2, ω), where ω is a primitive cube root of unity, Galois group of finite a extension of a finite field.
Lecture 2. Cyclotomic fields, cyclotomic polynomials, Galois group of cyclotomic fields; Artin’s theorem on the fixed field of a finite automorphism group of a field.
Lecture 3. Fundamental theorem of Galois Theory (FTGT), illustrations, Galois group of separable cubic polynomials, roots of unity in any field, cyclicity of radical extensions K( n√a), a ∈ K, when the ground field K contains distinct nth roots of unity.
Lecture 4. Applications of FTGT: Symmetric functions, symmetric functions are rational functions of elementary symmetric functions, discriminant of polynomial, criterion for a Galois group to be subgroup of the alternating group, proof of Fundamental Theorem of Algebra via FTGT, constructibility of regular n-gons (Fermat primes), solution of inverse Galois problem for finite abelian groups.
- Field Theory: IVth week by Prof. Dilip Patil
Starting with equivalent definitions of Galois extensions, in some examples Galois groups were calculated using groups actions. A characterisation of Cyclic Galois extensions using Hilbert’s theorem 90 was done. Roots of unity, Galois groups of Cyclotomic extensions and Galois groups of finite field extensions were discussed. At the end solvability of radicals of polynomials over arbitrary fields and their relations to Galois groups of their splitting fields was done. The last part was sketchy and not all complete proofs were given as lack of time and prerequisites of the participants. Many of them were fresh even in AFS III without attending AFS I or AFS II. I hope these comments are taken in a right spirit and used to improve further AFSs.

point, material on harmonic functions from your book was very good and was extremely useful. Students’ response was very good. Some Participants felt that during 4th week some topics were much above their head. Can you help the students during the next AFS-III.
- Topology: I st week by Prof. Manoj Keshri
Four lectures of 90 minutes each.
Lecture 1. I introduced some examples asking them whether they are homeomorphic, and introduced homotopy of two maps, problem whether in a triagle, if two maps are given, can one find the third one so that the diagram commutes.
Lecture 2. I defined the cofibration, retraction, (strong) deformation retraction etc and relations between them ware done in tutorial.
Lecture 3. I introduced path homotopy, definition of π1(X) etc.
Lecture 4 was π1(S1) = Z (only statement), Van-Kampen theorem (statement) and some applications of V-K, e.g. π1 of torus, figure eight, R3 \ (x − axis ) etc.; Brouwer fixed point theorem was also done.

Path and Homotopy lifting properties of the covering projection was discussed. The statement that covering projections are fibrations was proved.In the third lecture, the lifting problem was discussed with respect to the covering projection and necessary and sufficient conditions obtained for the same. The deck transformation groups were introduced, the relation of the deck transformation group with the fundamental group was discussed. Normal coverings were introduced and equivalent conditions for a covering to be normal were discussed.In the fourth lecture, the equivalence of coverings were introduced and the classification for coverings was taken up, leading to the one one correspondence between the equivalence classes of coverings and conjugacy classes of subgroups of the fundamental group for connected, locally path connected, semi locally simply connected spaces.

How To Reach
How to reach University of Pune
University of Pune is on the University Road, and it is about 5 km from the Main Railway Station and Main Bus stand.
The nearest Railway Station is Shivajinagar Railway Station (3km) and it is most convenient while coming from Mumbai side, but one should make sure that the train stops there. The autorickshaw fare is about 10 times the meter reading.
From airport the University is about 16 km.
When one enters the university there are 2 roads, take the right road to go to Mathematics Dept. or to University Guest House/ Univ. SET Guest House. Dept. of Math. comes first on this road on the left side, and it is a building with Green Colour Fence. To go to SET Guest House, one goes ahead and at the end turns to the left, to go near main Guest House. The main Guest House is very near the main building (with Flag) and is next to VC Bungalow and from the main Guest House, a road goes to IUCAA. The SET Guest House is located on this road about 150 meters from main Guest House on the right side.
WELCOME to AFS-III. This page will help you to take the best advantage from this programme. You should remember that in just four weeks duration you are going to be exposed some good mathematics at masters level which is normally covered in a semester. AFS-III is the third stage of such a programme. However, most of you have perhaps not attended the first two stages. Therefore, it becomes necessary for you to make at least a bit of preparation to attend this school. Even otherwise, it is good to come well-prepared to interact with several experts you will meet during this short duration of the school. The necessaary pre-requisites please click on:
