Uniqueness of Meromorphic Functions Weighed Sharing Three Sets

LI Ji-long,SHI Zhong-chunCollege of Mathematics and Physics,Chongqing University,Chongqing 400030,China  
Using the idea of weighted sharing,deal with the uniqueness problems on meromorphic functions that sharing three sets.Mainly the authors proved the following results: Let f and g be two meromorphic functions,ki(i=1,2,3) be non-negative integers,n be an integer not less than 2,and(an-a-2)(bcn-b-c)2bcn where k1+1=a,k2+1=b,k3+1=c,then f≡tg where tn=1 or fg≡s where 0 and ∞ are lacunary values of f and g,and sn=1.
