In this paper, we extend the notions of states and measures presented in Dvurečenskij and Pulmannová (2000) [12], to the case of pseudo-BCK algebras and study similar properties. We prove that, under some conditions, the notion of a state in the sense of Dvurečenskij and Pulmannová (2000) [12], coincides with the Bosbach state, and we extend to the case of pseudo-BCK algebras some results proved by Kühr only for pseudo-BCK semilattices. We characterize extremal states, and show that the quotient pseudo-BCK algebra over the kernel of a measure can be embedded into the negative cone of an archimedean ℓ-group. Additionally, we introduce a Borel state and using results by Kühr and Mundici (2007) [28], we prove a relationship between de Finetti maps, Bosbach states and Borel states.
