MTH421 Number Theory
Instructor : Anupam Kumar Singh, IISER Pune
Schedule : January - April 2011
Prerequisite : Rings, Modules, Field Extensions, Galois Theory
Objective : The course is meant for 4th year students with good background in Algebra. This is a basic course in Algebraic Number Theory. The subject was developed to solve one of the most famous problems in Mathematics : Fermat's Last Theorem. In this course we will see how one can solve the problem partially using this theory and completely if you make a mistake.
Content : Number Fields, Ring of Integers, Dedekind Domains, Solving Polynomials, Integral Bases, Ideal factorization, Ideal Class Group, Finiteness of Class group, Dirichlet's Unit Theorem, Solution of FLT in a special case.
Evaluation : 3 tests (20% each) + a project (30%) + teacher's assessment (10%)
