TY - JOUR JF - IJMSI JO - IJMSI VL - 8 IS - 2 PY - 2013 Y1 - 2013/10/01 TI - Weak complete parts in semihypergroups TT - N2 - In this article we generalize the notion of complete parts, by introducing a weaker condition in definition. Using this generalization we define and analyse a new class of semihypergroups, which are called weak complete semihypergroups. Complete parts were introduced about 40 years ago by M. Koskas and they represent a basic notion of hyperstucture theory, utilized in constructing an important class of subhypergroups of a hypergroup and also they are used to define complete hypergroups.
