Excerpt
Smarandache inversion sequence
Abstract We study the Smarandache inversion sequence which is a new concept, related sequences, conjectures, properties, and problems. This study was conducted by using (Maple 8){a computer Algebra System.
Keywords Smarandache inversion, Smarandache reverse sequence.
Introduction
In [1], C.Ashbacher, studied the Smarandache reverse sequence:
1; 21; 321; 4321; 54321; 654321; 7654321; 87654321; 987654321; 10987654321; 1110987654321; (1) and he checked the _rst 35 elements and no prime were found. I will study sequence (1), from different point of view than C. Ashbacher. The importance of this sequence is to consider the place value of digits for example the number 1110987654321, to be considered with its digits like this : 11; 10; 9; 8; 7; 6; 5; 4; 3; 2; 1, and so on. (This consideration is the soul of this study because our aim is to study all relations like this (without loss of generality).
Definition. The value of the Smarandache Inversions (SI) of a positive integers, is the number of the relations i > j ( i and j are the digits of the positive integer that we concern with it), where i always in the left of j as the case of all numbers in (1). I will study the following cases of above equation.
Examples. The number 1234 has no inversions ((SI) = 0, or zero inversion), also the number 1, while the number 4321 has 6 inversions, because 4 > 3 > 2 > 1, 3 > 2 > 1, and 2 > 1. The number 1110987654321 has 55 inversions, and 1342 has two inversions. So our interest will be of the numbers in Smarandache reverse sequence i.e. (1), because it has mathematical patterns and interesting properties.
