The Complexity of Early Deciding Set Agreement
Set agreement, where processors decisions constitute a set of outputs, is notoriously harder to analyze than consensus where the decisions are restricted to a single output. This ...

X-maps: An Efficient Model for Non-manifold Modeling
Abstract--Many representation schemes have been proposed to deal with non-manifold and mixed dimensionalities objects. A majority of those models are based on incidence graphs and ...

A Topological Constraint Language with Component Counting
A topological constraint language is a formal language whose variables range over certain subsets of topological spaces, and whose nonlogical primitives are interpreted as topologi...

Querying Spatial Databases via Topological Invariants
The paper investigates the use of topological annotations (called topological invariants) to answer topological queries in spatial databases. The focus is on the translation of to...

Self-Repelling Snakes for Topology-Preserving Segmentation Models
The implicit framework of the level-set method has several advantages when tracking propagating fronts. Indeed, the evolving contour is embedded in a higher dimensional level-set f...

Dynamic topological logic
Dynamic Topological Logic provides a context for studying the confluence of the topological semantics for S4, based on topological spaces rather than Kripke frames; topological dy...

Topological Perspective on the Hybrid Proof Rules
We consider the non-orthodox proof rules of hybrid logic from the viewpoint of topological semantics. Topological semantics is more general than Kripke semantics. We show that the...

Stability of Critical Points with Interval Persistence
Scalar functions defined on a topological space Ω are at the core of many applications such as shape matching, visualization and physical simulations. Topological persistence i...

The Hadwiger Number of Jordan Regions is Unbounded
We show that for every n > 0 there is a planar topological disk A0 and n translates A1, A2, . . . , An of A0 such that the interiors of A0, . . . An are pairwise disjoint, but ...

GEncode: Geometry-driven compression for General Meshes
Performances of actual mesh compression algorithms vary significantly depending on the type of model it encodes. These methods rely on prior assumptions on the mesh to be efficient...
