  In this paper, some properties and applications of MV-algebras are provided.
We define a Fibonacci sequence in an MV-algebra and we prove that such a
stationary sequence gives us an idempotent element. Taking into account of the
representation of a finite MV-agebra, by using Boolean elements of this
algebra, we prove that such a sequence is always stationary and is not periodic
as in the situation when such a sequence is studied on the group (Zn; +), the
group of integers modulo n. Moreover, as an application in Coding Theory, to a
Boolean algebra is attached a binary block code and is proved that, under some
conditions, the converse is also true.
