Here we analyze the partition function of the dimer model on a $2M\times 2N$ checkerboard lattice wrapped on…

]]>We investigate the Fokker-Planck description of the equal-time statistics of the three-dimensional Lorenz attractor with additive white noise. The invariant measure is found by computing the zero (or null) mode of the linear Fokker-Planck operator as a problem of sparse linear algebra. Two variants …
