Abstract

We will characterize isomorphisms from the adjoint of a certain tridiag-onal algebra <TEX>$AlgL_{2n}$</TEX> onto <TEX>$AlgL_{2n}$</TEX>. In this paper the following are proved: A map <TEX>$\Phi{\;}:{\;}(AlgL_{2n})^{*}{\;}{\longrightarrow}{\;}AlgL_{2n}$</TEX> is an isomorphism if and only if there exists an operator S in <TEX>$AlgL_{2n}$</TEX> with all diagonal entries are 1 and an invertible backward diagonal operator B such that <TEX>${\Phi}(A){\;}={\;}SBAB^{-1}S^{-1}$</TEX>.
