Uniquely Remotal Sets in $c_0$-sums and $\ell^\infty$-sums of Fuzzy Normed Spaces

Let $(X, N)$ be a fuzzy normed space and $A$ be a fuzzy bounded subset of $X$. We define fuzzy $\ell^\infty$-sums and fuzzy $c_0$-sums of fuzzy normed spaces. Then we will show that in these spaces, all fuzzy uniquely remotal sets are singletons.
