Trace conjecture. The fourth power of $A$ should have finite trace:

Kinetic conjecture. In a leading Feynman diagram, the sum of these phases vanishes for every choice of internal wave numbers, with the cancellation holding for $m=0,\ldots,n$.

Kinetic conjecture. In a leading Feynman diagram, the Kirchhoff rule never forces an identification of the form $\delta(k_j)$ with some wave vector $k_j$. In addition, the sum of t…

Let … by $/$ in the interaction parameter, and let $(k)$ be the dispersion relation whose square is the Fourier transform of the lattice operator $2(-\Delta+1)$. For macroscopic va…
