A nicer proof of smoothness:

Simplicial vs smooth

Some interesting references on creating stacky fans from Cartan matrices: http://www.mi.uni-koeln.de/DFG-Schwerpunkt/VortraegeThurnau/MarkBlume.pdf#page=21&zoom=auto,-91,249

Completeness and properness:

Distinguished points:

Orbits in terms of quotient lattices:

Orbit-cone correspondence:

Star fans:

Introducing a ray into a cone to subdivide modifies \(X_\Sigma\) at the distinguished point of \(U_\sigma\).

Stellar refinements:

Singular and smooth loci:

Divisors

Restriction:

example computations of divisor class groups

Characterizing when Weil = Cartier:

Intersection products
