A fluctuating boundary integral method for Brownian suspensions

1 code implementation5 Sep 2017 Yuanxun Bao, Manas Rachh, Eric Keaveny, Leslie Greengard, Aleksandar Donev

We present a fluctuating boundary integral method (FBIM) for overdamped Brownian Dynamics (BD) of two-dimensional periodic suspensions of rigid particles of complex shape immersed in a Stokes fluid.

On the Diffusion Geometry of Graph Laplacians and Applications

We study directed, weighted graphs $G=(V, E)$ and consider the (not necessarily symmetric) averaging operator $$ (\mathcal{L}u)(i) = -\sum_{j \sim_{} i}{p_{ij} (u(j) - u(i))},$$ where $p_{ij}$ are normalized edge weights.
