On The Inertia Conjecture for Alternating group Covers

Algebraic Geometry 2020-11-11 v2

Abstract

The wild part of Abhyankar's Inertia Conjecture for a product of certain Alternating groups is shown for any algebraically closed field of odd characteristic. For dd a multiple of the characteristic of the base field, a new \'etale AdA_d-cover of the affine line is obtained using an explicit equation and it is shown that it has the minimal possible upper jump.

Comments

14 pages, comments are welcome. The statement of the Theorem 4.7 of the previous version is incorrect and is removed. Added new results, thus generalizing the number of factors involved in the product, but now restricting the degrees of the Alternating groups. Proofs and preliminaries have been made more concise. Corrected typos
