Abstract

Metallic Ratios are class of numbers which are irrationals. The well known Golden Ratio and Silver Ratio are special cases of sequences of Metallic Ratios. In this paper, after introducing Metallic Ratios formally, I have proved some interesting inequalities for powers of metallic ratios whose lower and upper bounds will be connected to Ramanujan Summation method leading to very interesting and new results. In this paper, I had extended the concept of Ramanujan Summation technique to the bounds of powers of metallic ratios. In Ramanujan Summation Method, Ramanujan showed that Ramanujan Sum of all even powers of positive integers is always zero. Similar to this, I had proved that Ramanaujan Summation of all even powers of lower bounds of Metallic ratios of order k is always -1/2. The result regarding computation of upper bounds of Metallic ratios through two previous lower bounds has been established. This result enables us to compute the Ramanujan Summation of Upper bounds of Metallic Ratios in terms of the corresponding Lower bounds. Further, I had shown that the Ramanujan Summation of Upper bounds of Metallic ratios of order 2r + 1 are equal to Upper bounds of Metallic ratios of order 2r + 2. In the final section, the computation of Ramanujan Summation values of lower and upper bounds for first eight powers of metallic powers were carried out. These values verify the theorems proved in this paper. The whole idea of assigning Ramanujan Summation to bounds of Metallic Ratios is very new and so the results obtained in this paper provide great insights and opens great scope towards understanding the behavior of metallic ratios.
