A note on the sum of reciprocals

Abstract

For a fixed positive integer mm and any partition m=m1+m2++mem = m_1 + m_2 + \cdots + m_e , there exists a sequence {ni}i=1k\{n_{i}\}_{i=1}^{k} of positive integers such that m=1n1+1n2++1nk,m=\frac{1}{n_{1}}+\frac{1}{n_{2}}+\cdots+\frac{1}{n_{k}}, with the property that partial sums of the series {1ni}i=1k\{\frac{1}{n_i}\}_{i=1}^{k} can only represent the integers with the form iImi\sum_{i\in I}m_i, where I{1,...,e}I\subset\{1,...,e\}.
