Staged tree models with toric structure
Christiane Görgen, Aida Maraj, Lisa Nicklasson
A staged tree model is a discrete statistical model encoding relationships between events. These models are realised by directed trees with coloured vertices. In algebro-geometric…

Products of polymatroids with the strong exchange property
Lisa Nicklasson
It was conjectured by White in 1980 that the toric ring associated to a matroid is defined by symmetric exchange relations. This conjecture was extended to discrete polymatroids by…
