On the Universal Space for Group Actions with Compact Isotropy
... Recall from the introduction the G-CW -complex E(G, F). In particular, notice that we only assume that the fixed point sets E(G, F)H for H ∈ F are weakly contractible, and not necessarily contractible. If G is discrete, then each fixed point set E(G, F)H has the homotopy type of a CW -complex and is ...

A NOTE ON A THEOREM OF AX 1. Introduction In [1]
... used by Boris Zilber [20] to prove Weak CIT, a weak version of Conjecture on Intersection with Tori (CIT) stated in [20]. CIT is a finiteness statement about intersections of subtori of a given torus with certain subvarieties of this torus. Weak CIT was crucial in the bad field construction [3]. Dur ...

Notes on quotients and group actions
... The action of G on M is called free if for each x ∈ M the stabilizer subgroup Gx = {g ∈ G | xg = x} is trivial. It is called free and properly discontinuous if for each x ∈ M there exists a neighborhood U such that U ∩ U g = ∅ for every g ∈ G, g 6= e. Equivalently, this means that the sets U g, for ...

Sec. 2.7: Prove Angle Pair Relationships
... When two lines intersect, they form four angles. The angles that together form a straight line are called linear pairs of angles. Angle 1 and 2, Angle 2 and 3, Angle 3 and 4, and Angle 4 and 1 are linear pairs of angles. ...
