講座簡介:
Sobriety and well-filterdness are two of the most important topological properties for non-Hausdorff spaces. They have played important roles in distinguishing the differences between spaces appeared in domain theory, as well as revealing the fine properties of various constructions of new dcpos from given ones. In this talk, I will present some new results on such properties. These results include a unified definition for such properties, an answer to a problem recently posed by Jung and the well-filterdness of the Smyth power domains.
