Maximizing Adaptivity in Hierarchical Topological Models
We present an approach to hierarchically encode the topology of functions over triangulated surfaces. We describe the topology of a function by its Morse-Smale complex, a well kno...

Hierarchical Heterogeneous Specifications
We propose a definition of hierarchical heterogeneous formal specifications, where each module is specified according to its own homogeneous logic. We focus on the specification st...

A Lattice-Based Approach to Hierarchical Clustering
The paper presents an approach to hierarchical clustering based on the use of a least general generalization (lgg) operator to induce a lattice structure of clusters and a categor...
