【 摘 要 】
Lin and Su classified $Amathcal{T}$-algebras of real rank zero. This class includes all $Amathbb{T}$-algebras of real rank zero as well as many ð¶*-algebras which are not stably finite. An $Amathcal{T}$-algebra often becomes an extension of an $Amathbb{T}$-algebra by an ð´ð¹-algebra. In this paper, we show that there is an essential extension of an $Amathbb{T}$-algebra by an ð´ð¹-algebra which is not an $Amathcal{T}$-algebra. We describe a characterization of an extension ð¸ of an $Amathbb{T}$-algebra by an ð´ð¹-algebra if ð¸ is an $Amathcal{T}$-algebra.
