摘要: Amd={(x1,…,xd)∈Rd:x1>0,…,xm>0,1≤md}为Rd(d≥2)中的角域.该文绘出了Amd上正调和函数的Martin表示,讨论了极小调和函数与条件Brown运动的一个0-1律之间的关系,并给出了Amd上极小调和函数的表现形式,

Abstract: Let Amd={x1,…,xd)∈Rd:x1>0,…,xm>0,1 ≤ md} be the angular domain in Rd(d≥2). In this paper we obtain the Martin's representation of positive harmonic functions in Amd,the relationship between the minimal harmonic functions and a zero-one law for conditioned Brownian motion are investigated, the representaive forms of the minimal harmonic functions in Amd are also presented.

Key words: Harmonic functions, Martin's representation, minimal harmonic functions, condi-tioned Brownian motion
