Let $I_A$ be a toric ideal, and let the true degree of a circuit of $A$ mean the degree computed without dividing by the common factor $c$ in the circuit formula. Sturmfels's conje…

Let $W a a$ be a rational linear subspace. For $z a a a Wcapmathbb{Z}^n$, a conformal circuit decomposition is a representation of $z$ as a sum of conformal circuit vectors. A vect…

Graver-basis edge-connectivity conjecture. In all Graver fiber graphs of $A$, the edge-connectivity equals the minimal degree.
