On toric and toroidal foliations
Chih-Wei Chang, Yen-An Chen
In this paper, we provide toric descriptions for various foliation singularities on toric varieties, especially for non-dicritical singularities and F-dlt singularities. We then sh…

Tropical linear series and matroids
Chih-Wei Chang, Matthew Dupraz, Hernan Iriarte +4
We study a notion of tropical linear series on metric graphs that combines two essential properties of tropicalizations of linear series on algebraic curves: the Baker-Norine rank…

Boundedness of toric foliations
Chih-Wei Chang, Yen-An Chen
We discuss boundedness of toric Fano foliations and connectedness of its dicritical and singular loci. Moreover, we show the set of interpolated -lcts for the toric foliations…
