Ahmed Abujoda,Panagiotis Papadimitrioum function arises, usually in an actual physical context. As already emphasized in the Introduction, in order to apply probabilistic methods, we must have an experiment which can be repeated many times under similar conditions and which can lead to different outcomes.

C. Bouras,V. Kapoulas,E. Tsanai consider the more general case of the complex-valued function .(.). Assuming that . = 0 for . > . and . < 0, we can write the corresponding generalization of the result (2.5) in the form ..
