Title: The Ramification Filtration in Local Kummerian Extensions
Speaker: C. S. Dalawat, Harish-Chandra Research Institute
Abstract: We show that the ramification filtration (in the upper numbering) on the maximal Kummerian extension of exponent p of a finite extension of Qp is dual to the natural filtration on the multiplicative group.
The talk will be completely elementary.
