Remarks on a paper of Guy Henniart

... Let K/E be an infinite Galois extension of p-adic local fields. Let v be a jump for the upper numbering filtration and define α = inf{α ∈ R | Gal(K/E)α ⊆ Gal(K/E)v }. Then α is strictly smaller than v. 1.5. Wild, homogeneous local Galois representations All fields are non-Archimedean local containin ...

Morphisms in Logic, Topology, and Formal Concept Analysis

... ping on models in the opposite direction, with the property that the image of a formula relates to a given model if and only if the image of the model relates to the formula. These morphisms have several advantages: other than being motivated in logical terms, they can easily be described for arbitr ...

... Topology is a generalization of order Verify that for an ordered set (X , 6) the set τ = {A ∈ P(X ) | ∀x∈A ∀y ∈X [(x 6 y ) ⇒ (y ∈ A)]} is a topology on X . It is called the Alexandroff topology of (X , 6). Show that two different orders on the same set give rise to two different Alexandroff topologi ...
