Workshop on Topology: Identifying Order in Complex Systems

Persistent Cohomology and Circular Coordinates
Vin de Silva
4:30pm|University of Pennsylvania, David Rittenhouse Lab., Room A6

High-dimensional data sets often carry meaningful low-dimensional structures. There are different ways of extracting such structural information. The classic (circa 2000, with some anticipation in the 1990s) strategy of nonlinear dimensionality...

Using Computational Algebraic Topology to Characterize Chromosome Instability in Cancer
Javier Arsuaga
3:00pm|University of Pennsylvania, David Rittenhouse Lab., Room A6

DNA copy number abnormalities (CNAs) play an important role in cancer, and are associated with tumor progression as well as clinical outcome. Using microarray based comparative genomic hybridization (CGH), analysis of CNAs across large cohorts of...
