Abstract

This talk describes recent Joint work with Sergio Rajsbaum [3].

For models of concurrent computation in which processes may fail by crashing, each possible computation can be characterized as a simplicial complex, a geometric structure constructed by “gluing together” simplexes in a regular manner [6]. Informally, a complex is k-connected if it has no “holes” in dimension k or lower. It is known that if the complex corresponding to every such computation is k-connected, then one cannot solve (k + 1)-set agreement [4,5,6].
