Abstract

Let (T,,,)(T,\langle \cdot, \cdot, \cdot \rangle) be a Leibniz triple system of arbitrary dimension, over an arbitrary base field F{\mathbb F}. A basis B={ei}iI{\mathcal B} = \{e_{i}\}_{i \in I} of TT is called multiplicative if for any i,j,kIi,j,k \in I we have that ei,ej,ekFer\langle e_i,e_j,e_k\rangle\in {\mathbb F}e_r for some rIr \in I. We show that if TT admits a multiplicative basis then it decomposes as the orthogonal direct sum T=kIkT= \bigoplus_k{\mathfrak I}_k of well-described ideals Ik{\mathfrak I}_k admitting each one a multiplicative basis. Also the minimality of TT is characterized in terms of the multiplicative basis and it is shown that, under a mild condition, the above direct sum is by means of the family of its minimal ideals.
