DESCRIPTION:Claudia Landi (UniMORE)\nIn the last twenty years\, computatio
 nal topology has contributed with a number of methods to deal with the tas
 k of describing and comparing shapes. The ultimate goal of this research a
 rea is to provide topological ground for classification and retrieval of d
 igital shapes contained in a database based on content. The general pipeli
 ne in this field is to associate with each shape a shape descriptor and th
 en recast the shape comparison problem as a metric problem on shape descri
 ptors. The talk will report on the state of the art of some popular topolo
 gical shape descriptors coming from the Persistent Homology Theory. In par
 ticular\, persistence diagrams with the bottleneck distance and persistenc
 e modules with the interleaving distance will be reviewed and shown to sat
 isfy stability and optimality properties.
