  The interplay between interparticle interactions and topological features may
result in unusual phenomena. Interestingly, interactions may induce topological
features in an originally trivial system, as we illustrate for the case of a
one-dimensional two-component Hubbard model in which one component is subjected
to Su-Schrieffer-Heeger(SSH) dimerization, whereas the other one is not. We
show that due to inter-component interactions the topological properties of one
component are induced in the originally trivial one. Although for large
interactions topological inheritance may be readily explained by on-site
pairing, we show that the threshold for full inheritance occurs at weak
interactions, for which the components are not yet paired. We illustrate this
inheritance by discussing both bulk and edge properties, as well as dynamical
observables as mean chiral displacement and charge pumping.
