β¦ Synopsis
This paper presents two uniqueness theorems for the family of hierarchical classes models, a collection of order preserving Boolean decomposition models for binary N-way N-mode data. The theorems are compared with uniqueness results for the closely related family of N-way N-mode principal component models. It is concluded that the two-way two-mode PCA and N-way N-mode TuckerN models suffer more from a lack of identifiability than their hierarchical classes analogues, whereas the uniqueness conditions for N-way N-mode PARAFAC/CANDECOMP models are less restrictive than the ones derived for their N-way Nmode hierarchical classes counterparts.

## Abstract In this paper, we use the coincidence degree theory to establish new results on the existence and uniqueness of __T__ βperiodic solutions for a class of nonlinear __n__ βth order differential equations with delays of the form __x__^(__n__)^(__t__) + __f__ (__x__^(__nβ__ 1)^(__t__)) + _
