右LCM幺半群的$C^*$ -代数及其平衡态

$C^*$-algebras of right LCM monoids and their equilibrium states

Nathan Brownlowe, Nadia S. Larsen, Jacqui Ramagge, Nicolai Stammeier

摘要:

通过将核半群$C^*$-代数隔离为Fock型模的系数代数,研究了右LCM幺半群的$C^*$ -代数的内部结构,其中满半群$C^*$ -代数在该模上有一个左作用.在半群具有广义标度的情况下,对半群$C^*$ -代数上的KMS-态进行了分类,并给出了KMS $_β$ -态在逆温度$β$下在临界区间内唯一的充分条件.

英文摘要:

We study the internal structure of $C^*$-algebras of right LCM monoids by means of isolating the core semigroup $C^*$-algebra as the coefficient algebra of a Fock-type module on which the full semigroup $C^*$-algebra admits a left action. If the semigroup has a generalised scale, we classify the KMS-states for the associated time evolution on the semigroup $C^*$-algebra, and provide sufficient conditions for uniqueness of the KMS$_β$-state at inverse temperature $β$ in a critical interval.
