摘要:对于任意实数x,Sdfp(x)=min{m∈N:px≤m!!},x∈(1,∞);Sdf*p(x)=max{m∈N:m!!≤px},x∈(1,∞).研究了这2个函数的均值性质,并得出2个有趣的渐进公式.

Abstract: To any real number x,the Smarandarche function is defined as Sdfp(x)=min{m∈N:px≤m!!},x∈(1,∞),and the antithesis as Sdfp(x)=max{m∈N:m!!≤px},x∈(1,∞).The asymptotic properties of these two functions are studied;thus,the asymptotic formula about their is obtained.
