Abstract

In this paper, we consider a generalized Toeplitz algebra T(PN×)\mathcal{T} ( \mathrm{P}\rtimes\Bbb N^{\times}) for a non-quasi-lattice ordered semigroup PN× \mathrm{P}\rtimes\Bbb N^{\times} where PN× \mathrm{P}\rtimes\Bbb N^{\times} is a semidirect product of an additive semigroup P={0,2,3,} \mathrm{P} = \{0, 2, 3, \cdots \} by a multiplicative positive natural numbers semigroup N× \Bbb N^{\times}. And also we compute the values of the KMS state of the natural CC^*-dynamical system (T(PN×),R,σ).( \mathcal{T} ( \mathrm{P}\rtimes\Bbb N^{\times}), \Bbb R, \sigma ).
