Abstract

In this paper, we will investigate further properties of -schemes introduced in [Tak]. The category of -schemes possesses many properties of the category of coherent schemes, and in addition, it is co-complete and complete. There is the universal compactification, namely, the Zariski-Riemann space in the category of -schemes. We compare it with the classical Zariski-Riemann space, and characterize the latter by a left adjoint.
