Description

I give a canonical construction of the sheaf of log structures on a generic toroidal crossing space that makes it possible to make (singular) log structures explicitly and efficiently. I will sketch future applications to smoothing of toric Fano varieties and log birational geometry. I will not assume previous knowledge of log structure. This is joint work with Helge Ruddat.
