摘要 本文首先给出关于子基的半Ti(i=0,1,2)、半正则和半正规空间的定义及其等价刻画,并证明关于子基的半Ti(i=0,1,2)在关于子基的同胚开映射下保持,而关于子基的半正则(正规)在关于子基的同胚连续开映射下保持. In this paper,it gives the definitions of β-semi-Ti(i=0,1,2)、β-semi-regular and β-semi-normal and their equivalent characterizations.What's more,it proves that β-semi-Ti(i=0,1,2) can be preserved by(α,β)-homeomorphism-open-mapping and β-semi-regular(normal) can be preserved by(α,β)-homeomorphism -open-continuous-mapping.
