Duality in Computer Science (Dagstuhl Seminar 15441)

Authors: Mai Gehrke, Achim Jung, Victor Selivanov, and Dieter Spreen

Published in: Dagstuhl Reports, Volume 5, Issue 10 (2016)

Abstract
This report documents the programme and outcomes of Dagstuhl Seminar 15441 `Duality in Computer Science'. This seminar served as a follow-up seminar to the seminar `Duality in Computer Science' (Dagstuhl Seminar 13311). In this seminar, we focused on applications of duality to semantics for probability in computation, to algebra and coalgebra, and on applications in complexity theory. A key objective of this seminar was to bring together researchers from these communities within computer science as well as from mathematics with the goal of uncovering commonalities, forging new collaborations, and sharing tools and techniques between areas based on their common use of topological methods and duality.

Duality in Computer Science (Dagstuhl Seminar 13311)

Authors: Mai Gehrke, Jean-Eric Pin, Victor Selivanov, and Dieter Spreen

Published in: Dagstuhl Reports, Volume 3, Issue 7 (2013)

Abstract
Duality allows one to move between the two worlds: the world of certain algebras of properties and a spacial world of individuals, thereby leading to a change of perspective that may, and often does, lead to new insights. Dualities have given rise to active research in a number of areas of theoretical computer science. Dagstuhl Seminar 13311 "Duality in Computer Science" was held to stimulate research in this area. This report collects the ideas that were presented and discussed during the course of the seminar.

Computing with Infinite Data: Topological and Logical Foundations (Dagstuhl Seminar 11411)

Authors: Ulrich Berger, Vasco Brattka, Victor Selivanov, Dieter Spreen, and Hideki Tsuiki

Published in: Dagstuhl Reports, Volume 1, Issue 10 (2012)

Abstract
There is a large gap between mathematical structures and the structures computer implementations are based on. To stimulate research to overcome this---especially for infinitary structures---highly non-trivial problem the Dagstuhl Seminar 11411 ``Computing with Infinite Data: Topological and Logical Foundations'' was held. This report collects the ideas that were presented and discussed during the course of the seminar.

04351 Summary – Spatial Representation: Discrete vs. Continuous Computational Models

Authors: Ralph Kopperman, Prakash Panangaden, Michael B. Smyth, Dieter Spreen, and Julian Webster

Published in: Dagstuhl Seminar Proceedings, Volume 4351, Spatial Representation: Discrete vs. Continuous Computational Models (2005)

Abstract
Topological notions and methods are used in various areas of the physical sciences and engineering, and therefore computer processing of topological data is important. Separate from this, but closely related, are computer science uses of topology: applications to programming language semantics and computing with exact real numbers are important examples. The seminar concentrated on an important approach, which is basic to all these applications, i.e. spatial representation.
