      Conditional demimartingales and related results 

      Christofides, Tasos C.; Hadjikyriakou, M. (2013)
      In this paper we deal with the classes of F-demimartingales and conditional N-demimartingales and for these new classes of random objects we provide a number of maximal and moment inequalities as well as related asymptotic ...

      Maximal inequalities and convergence results for generalized U-statistics 

      Christofides, Tasos C.; Serfling, R. J. (1990)
      We present some key probability inequalities and convergence results for multisample, or 'generalized' U-statistics. The reverse martingale structure of generalized U-statistic is exploited to obtain a useful Kolmogorov-type ...
