Counting Extensions of $\mathfrak{p}$-Adic Fields with Given Invariants

Brian Sinclair

Published 2015-12-22Version 1

We give two specializations of Krasner's mass formula. The first formula yields the number of extensions of a $\mathfrak{p}$-adic field with given, inertia degree, ramification index, discriminant, and ramification polygon. We then refine this formula further to the case where an additional invariant related to the residual polynomials of the segments of the ramification polygon is given.
