Spider Diagrams of Order and a Hierarchy of Star-Free Regular Languages [chapter]

Aidan Delaney, John Taylor, Simon Thompson
Lecture Notes in Computer Science  
In this paper we consider relationships between spider diagrams of order (an extension of spider diagrams) and the star-free subset of regular languages.  ...  We establish that star-free languages are definable by spider diagrams of order equipped with the product operator and, based on this relationship, spider diagrams of order are as expressive as first order  ...  Comparing classes of regular languages and spider diagrams In this section we prove that all star-free regular languages are definable using spider diagrams of order.  ...

On the expressiveness of spider diagrams and commutative star-free regular languages

Aidan Delaney, Gem Stapleton, John Taylor, Simon Thompson
2013 Journal of Visual Languages and Computing  
In summary, we establish that spider diagrams define precisely: (a) languages definable in MFOL[ ¼], (b) the commutative star-free regular languages, and (c) finite unions of the form K G n , as just described  ...  We note that it was previously established that spider diagrams define commutative star-free languages. As a corollary, all languages of the form K G n are commutative star-free languages.  ...  Acknowledgements This research forms part of the Defining Regular Languages with Diagrams (EPSRC Grant EP/H012311/1) and Sketching Euler Diagrams (EPSRC Grant EP/H048480/1) projects.  ...

Nominal and verbal number in Bilugu Opo

Joshua A.G. Smolders
2019 Studies in African Linguistics  
Opuuo, T'apo [lgn]), a Koman language spoken in Ethiopia and South Sudan, has complex and interesting systems of both NOMINAL NUMBER and VERBAL NUMBER.  ...  This paper provides a description and analysis of these systems as found in the Bilugu dialect of Ethiopia, using Corbett's (2000) model of number systems as a theoretical framework.  ...  and that has no regular form.  ...

Junkspace

Rem Koolhaas
2002 October  
Valley cultures were thought to be the most resistant to Junkspace: at GVZ you can still see a universe of rules, order, hierarchy, neatness, coordination, poised moments before its implosion, but at ZHR  ...  Like a substance that could have condensed in any other form, Junkspace is a domain of feigned, simulated order, a kingdom of morphing.  ...
