Abstract
In this paper, we introduce FS-coalgebras, which provide solutions
of FS-equations and also solution of
braid equations considered by Caenepeel, Militaru and Zhu.
FS-coalgebras are constructed by using
FS-equations and Harrison cocycles.
As applications, we prove that every bialgebra
H is an FS-bialgebra if and only if there is a
two-sided integral α in
