    Arxiv HEP-TH (high energy physics theory) citation graph is from the e-print   
    arXiv and covers all the citations within a dataset of 27,770 papers with      
    352,807 edges. If a paper i cites paper j, the graph contains a directed edge  
    from i to j. If a paper cites, or is cited by, a paper outside the dataset, the
    graph does not contain any information about this.                             
    The data covers papers in the period from January 1993 to April 2003 (124      
    months). It begins within a few months of the inception of the arXiv, and thus 
    represents essentially the complete history of its HEP-TH section.             
    The data was originally released as a part of 2003 KDD Cup.

          We study the thermodynamics of the confined and unconfined phases of     
        superconformal Yang-Mills in finite volume and at large N using the AdS/CFT
        correspondence. We discuss the necessary conditions for a smooth phase     
        crossover and obtain an N-dependent curve for the phase boundary.          
    NOTE: an identical version this problem already appears in the UF Collection:  
    cit-HepTh           Pajek/HEP-th-new is identical to the                       
                        SNAP/cit-HeptTh graph.  Since it's small, I have           
                        decided to include both in the collection, to              
                        keep the SNAP/ collection complete.
