In topological data analysis and visualization, topological descriptors such as persistence
diagrams, merge trees, contour trees, Reeb graphs, and Morse–Smale complexes play an …

We introduce time‐varying extremum graph (tveg), a topological structure to support
visualization and analysis of a time‐varying scalar field. The extremum graph is a sub …

Morse complexes and Morse-Smale complexes are topological descriptors popular in
topology-based visualization. Comparing these complexes plays an important role in their …

Dynamic hierarchical data describes phenomena in a wide range of domains, from file
management to demographics and business administration, as well as feature extraction …
