Abstract
Remarks about strengthening of the triangle inequality and its reverse inequality in normed spaces for two and more elements are collected. There is also a discussion on Fischer-Muszely equality for n-elements in a normed space. Some other estimates which follow from the triangle inequality are also presented.
