... The p-adic upper half-plane. Recall that Berkovich analytic spaces are defined over any (i.e., possibly Archimedean) complete valued field. In particular, A1,an does R make sense; as a topological space, it is the set of multiplicative semi-norms on R[T ] which extend the usual absolute value on R, ...

PARTIALIZATION OF CATEGORIES AND INVERSE BRAID
... appeared in the literature. The main example which we have in mind is the inverse braid monoid, defined and studied in [EL]. The idea is the following: the braid group can be realized as the mapping class group (of homeomorphisms with compact support) of a punctured plane. In Section 4 we define the ...

Stone duality above dimension zero

Likewise, one can consider not only equational theories but also arbitrary first-order theories over an arbitrary signature, whose axioms are constructed ...
