  It is possible to extend the bipartite quantum-memory-assisted entropic
uncertainty relation to the tripartite one in which the memory is split into
two parts. However, the uncertainty relation is usually applied to two
incompatible observables. Many researches have been made to generalize the
uncertainty relations to more than two observables. Although many relations
have been obtained for bipartite quantum-memory-assisted entropic uncertainty
relation for multiple measurements, the case of tripartite remains unstudied
yet. Until now, there has not been any tripartite quantum-memory-assisted
entropic uncertainty relation for multiple measurements. In this work, several
tripartite quantum-memory-assisted entropic uncertainty relations for multiple
measurements are obtained. The lower bounds of these relations have three terms
which depend on the complementarity of the observables, the conditional von
Neumann entropy, the Holevo quantity and the mutual information. Also, it is
shown one of the terms is related to the strong subadditivity inequality.
