Strongly Koszul edge rings

Takayuki Hibi, Kazunori Matsuda, Hidefumi Ohsugi

We classify the finite connected simple graphs whose edge rings are strongly Koszul. From the classification, it follows that if the edge ring is strongly Koszul, then its toric id…

Strong Koszulness of toric rings associated with stable set polytopes of trivially perfect graphs

Kazunori Matsuda

We give necessary and sufficient conditions for strong Koszulness of toric rings associated with the stable set polytope of graphs.
