Abstract

In this paper, we study a class of Cantor-integers {Cn}n1\{C_n\}_{n\geq 1} with the base conversion function f:{0,,m}{0,,p}f:\{0,\dots,m\}\to \{0,\dots,p\} being strictly increasing and satisfying f(0)=0f(0)=0 and f(m)=pf(m)=p. Firstly we provide an algorithm to compute the superior and inferior of the sequence {Cnnα}n1\left\{\frac{C_n}{n^{\alpha}}\right\}_{n\geq 1} where α=logm+1p+1\alpha =\log_{m+1}^{p+1}, and obtain the exact values of the superior and inferior when ff is a class of quadratic function. Secondly we show that the sequence {Cnnα}n1\left\{\frac{C_n}{n^{\alpha}}\right\}_{n\geq 1} is dense in the close interval with the endpoints being its inferior and superior respectively. As a consequence, (i) we get the upper and lower pointwise density 1/α1/\alpha-density of the self-similar measure supported on C\mathfrak{C} at 00, where C\mathfrak{C} is the Cantor set induced by Cantor-integers. (ii) the sequence {Cnnα}n1\{\frac{C_n}{n^{\alpha}}\}_{n\geq 1} does not have cumulative distribution function but have logarithmic distribution functions (given by a specific Lebesgue integral). Lastly we obtain the Mellin-Perron formula for the summation function of Cantor-integers. In addition, we investigate some analytic properties of the limit function induced by Cantor-integers.
