摘  要:
设δ(S_α)为集中作用在S_α={||×||=α|α>0,x∈R~p}上的δ函数,其定义为: [δ(S_α),φ(x)]=∫_(S_α)φ(x)ds.函数(r-α)~(-m)(m=1,2,…)在R~P中非连续点的集合为S_α。我们运用中性极限和收敛于δ(S_α)的δ序列,在S_α上定义了分布积(r-α)~(-m)oδ(S_α).

摘  要:
Let δ(S_α) be the delta function concentrated on S_α the sphere in R~p with cen- tre the origin and radius α>0. Then [δ(S_α),φ(x)] =∫_s φ(x)ds. The function (r-α)~(-m)for m = 1,2,…, where r=(x_1~2…+x_p~2)~1/2 is non-continuous in R~p, the set of all non-continuous points being S_α. Using the ncutrix limit and a sequcnce converging to δ(S_α), we de- fine the product of (r-α)~(-m)and δ(S_α).
