Abstract

We study the structure of a Leibniz triple system E\mathcal{E} graded by an arbitrary abelian group GG which is considered of arbitrary dimension and over an arbitrary base field K\mathbb{K}. We show that E\mathcal{E} is of the form E=U+[j]1/I[j]\mathcal{E}=U+\sum_{[j]\in \sum^{1}/\sim} I_{[j]} with UU a linear subspace of the 1-homogeneous component E1\mathcal{E}_{1} and any ideal I[j]I_{[j]} of E\mathcal{E}, satisfying {I[j],E,I[k]}={I[j],I[k],E}={E,I[j],I[k]}=0\{I_{[j]},\mathcal{E},I_{[k]}\} =\{I_{[j]},I_{[k]},\mathcal{E}\}=\{\mathcal{E},I_{[j]},I_{[k]}\}=0 if [j][k][j]\neq [k], where the relation \sim in 1={gG{1}:Lg0}\sum^{1}=\{g \in G \setminus \{1\} : L_{g}\neq 0\}, defined by ghg \sim h if and only if gg is connected to hh.
