On the Wielandt and Bhatt-Dedania Theorems

In this paper, we generalize a norm topology in Wielandts theorem for unital normed algebras and in Bhatt-Dedanias theorem for Banach algebras, with each element being a zero topological divisor, by using 2-normed algebra and 2-Banach algebra, respectively.
