Summary:

We study the analytic structure of the space of germs of an analytic function at the origin of ℂm, namely the space ℂ{z}, where z = (z1, …, zm), equipped with a convenient locally convex topology. We are particularly interested in studying the properties of analytic sets of ℂ{z} as defined by the vanishing loci of analytic maps. While we notice that ℂ{z} is not Baire we also prove it enjoys the analytic Baire property: the countable union of proper analytic sets of ℂ{z} has empty interior. This property underlies a quite natural notion of a generic property of ℂ{z}, for which we prove some dynamics-related theorems. We also initiate a program to tackle the task of characterizing glocal objects in some situations.
