... In any given term, then, there are two possible types of suffix: one that appears precisely once, e.g., i in aj bj xi , which is known as a free suffix ; and one that appears precisely twice, e.g., j in aj bj xi , which is known as a dummy suffix. It is an important precept of summation convention t ...
