This paper introduces a model for blu¢ng that is relevant when bets are sunk and only actions -not valuationsdetermine the winner. Predictions from poker are invalid in such nonzero-sum games. Blu¢ng (respectively Sandbagging) occurs when a weak (respectively strong) player seeks to deceive his opponent into thinking that he is strong (respectively weak). A player with a moderate valuation shou...

Recently, it was shown that genuine Ng-Ng chemical bonds are present in the endohedral fullerenes Ng(2)@C(60) in the case of Ng=Xe, while it is more debatable whether a chemical bond exist for Ng=Ar and Kr. The lighter homologues with helium and neon are weakly bonded van der Waals complexes. The presence of a noble gas dimer inside the cage is expected to modify the exohedral reactivity of the...

The This paper aims to consider and study some new properties in NG groups that consist of non-bijective transformations are not a subset symmetric groups. regularity these presents such as results. Moreover, definition anti-inverse is given. Some results studied.
