讲座主题: The m-step Solvable Mono-anabelian Geometry of Number fields (joint work with Mohamed Saidi)
讲座摘要: In this talk, we establish a group-theoretic algorithm, to reconstruct a number field together with its maximal m-step solvable extension from the maximal m+ 7-step solvable quotient of its absolute Galois group. Moreover, if the number field is an imaginary quadratic field or Q, we establish a group-theoretic algorithm to reconstruct that field from the maximal 4-step solvable quotient of its absolute Galois group.
