Inapproximability of the Independent Set Polynomial in the Complex PlaneDeterministic Counting, Probability, and Zeros of Partition Functions (Simons Institute workshop, 2019)2019-03-18
Shows Sharp-P hardness of approximating the independent-set polynomial (partition function) outside the cardioid region: approximating its norm or angle is…
