$2B_{p}$ and $4B_{p}$ are topologically conjugate

Let $\lambda B_{p}$, where $\lambda$ is a nonzero complex number, denote a constant-weighted backward shift operators on $l^{p}$ for $1\leq p<\infty$. In this article, we investigate, in topologically conjugacy, the complete classification for $\lambda B_{p}$.
