Explicit construction of semi-stable models of Lubin-Tate curves with low level. (English) Zbl 1327.14118

Summary: We construct semi-stable models of Lubin-Tate curves with level one or two, and determine their reductions. We also give a description of an action of a subgroup of the product group of the Weil group and the multiplicative group of the central division algebra of invariant \(1/2\) on the reductions.
