Generalized triangle inequality of the second type in quasi normed spaces
Generalized triangle inequality of the second type in quasi normed spaces
We investigate a generalized triangle inequality of the second type in the framework of quasi normed spaces.More precisely, by using the well-known Aoki-Rolewicz theorem and some quasi normed inequalities, we obtain some regions of R n which contain the set of all ntuples satisfying the mentioned inequality.Moreover, some reverse inclusions …
