报告题目:Formal Group Laws and Classical Reciprocity Laws
报告摘要:Formal group laws are formal power series in two variables over a commutative ring that satisfy certain associativity, unitality and commutativity axioms. They are applied in algebraic number theory and algebraic topology. As an example of this application, a new approach relating formal group laws and classical reciprocity laws is introduced. This allows one to deduce a reciprocity formula for higher residue symbols which, in particular, implies the quadratic and cubic reciprocity laws.
