WebWe introduce and study two new inferential challenges associated with the sequential detection of change in a high-dimensional mean vector. First, we seek a confidence interval for the changepoint, and second, we estimate the set of indices of coordinates in which the mean changes. We propose an online algorithm that produces an interval with ... Weblocal class field theory (Norm map) Let K be a local field, for example the p -adic numbers. In Neukirch's book "Algebraic number theory", there is the statement: if K contains the n …

Brauer groups and the reciprocity map

Webrelationship can be strengthened somewhat by a result of local class eld theory known as the Norm Limitation Theorem. We say Kis perfect if every nite extension of Kis … Webin the class group: if b(Z+Z˝ i) = Z+Z˝ i 0in Cl(K) then set ˙ b(j(˝ i)) = j(˝ i). This action of fractional ideals on the j-values descends to an action of the ideal class group on the j-values. Example 2.2. Let K = Q(p 31). The class number is 3 and ideals representing the di erent ideal classes are (1), p 2, p , where p 2= 2Z + (1+ p 31 the range bench cushions

Norm groups and class fields of formally real quasilocal fields

Web31 de jul. de 2005 · Download PDF Abstract: This paper establishes a relationship between finite extensions and norm groups of formally real quasilocal fields, which yields a generally nonabelian local class field theory, including analogues to the fundamental correspondence, the local reciprocity law and the norm limitation theorem.
