    • A note on the Ramsey number for small graphs 

      Vetrík, Tomáš; Jaradat, Mohammed M. M.; Bataineh, Mohammad S. ( Taylor and Francis Ltd. , 2022 , Article)
      Problems in the Ramsey theory form a well-known family of mathematical problems. We present the exact value of the Ramsey number R(θ6, W5), where θ6 is the set of theta graphs of order 6 and W5 is the wheel graph of order ...

    • The Ramsey number for two graphs of order 5 

      Bataineh M.S.; Vetrik T.; Jaradat M.M.M.; Rabaiah A.M.M. ( Taylor and Francis Ltd. , 2018 , Article)
      For two graphs F1 and F2, the Ramsey number R(F1, F2) is the smallest positive integer r such that for every graph G on r vertices, G contains F1 as a subgraph or the complement of G contains F2 as a subgraph. We present ...
