Benjamin Schweinhart

I am an Assistant Professor at George Mason University, in the Department of Mathematical Sciences. My research interests are stochastic, applied, and computational geometry and topology, and applications to percolation theory, materials science, statistical physics, and biology.

Software

Swatches: Local Structure Classification in Graphs. This software implements the methodology described in "Statistical Topology of Bond Networks with Applications to Silica" and "Topological Similarity of Random Cell Complexes and Applications."


Dimension Estimation with PH0. This software implements the methodology described in "Fractal Dimension Estimation with Persistent Homology: A Comparative Study," and includes C++ code to compute the PH0 dimensionand MATLAB code to compute the correlation dimension (written by J. Jaquette).
