Generalized group algebras and generalized measure algebras on non-discrete locally compact abelian groups

Jyunji Inoue, Sin-Ei Takahasi

Let $G$ be a non-discrete LCA group with the dual group $Γ$ . We define generalized group algebra, $L^{1} (G)$ , and generalized measure algebra, $M (G),$ on $G$ as…

Characterization of a generalized triangle inequality in normed spaces

F. Dadipour, M. S. Moslehian, J. M. Rassias +1

For a normed linear space $(X, ∣ \cdot ∣)$ and $p > 0$ we characterize all $n$ -tuples $(μ_{1}, ..., μ_{n}) \in R^{n}$ for which the generalized triangle inequality of the second type $…
